Last weekend, the 3D Printing Party in Burgos, Spain, broke the record for the most 3D printers printing simultaneously with their owners. However, that may not be the only record broken at the annual event.
At the University of Burgos in Spain last weekend, a 3D Printing Party took over from May 4th to 6th. During this time, the “biggest event for 3D printing in Spain” broke the world record for amateur 3D printers all working at the same time.
Impressively, the fourth year of the 3D Printing Party saw 161 machines printing simultaneously, controlled by their 210 owners. The party stole this title from the previous holder, the American Airwolf3D company who had 159.
As well as this record, MakerGal, a 3D printer design company in Galicia, believe they may have broken the world record for the longest 3D printed sword. It took the team 48 hours to create the 4.8 meters sword. They hope to take the record from previous holder, XRobots UK.
As well as being a great place for breaking records, the party also displays the capabilities and latest developments in the industry to all those attending. Better yet, it’s also a great way for fans of 3D printing all across Spain to get together.
Four Years of Bringing Together 3DP Makers and Fans
This year’s party is the first time it is located in Burgos. For the first few 3D Printing Parties, the location was León, Spain and saw 15,000 visits in three years.
Rodrigo Morales, one of the organizers, explains that the party “was born from the Clone Wars community – which tries to document everything necessary to build your own 3D printer – with the aim of getting to know each other and sharing knowledge and experiences.”
The website explains further, “Clone Wars is a group within the RepRap community… We also collect information such as location of local businesses, members of the group that have a printer near you… data in general that can help you with your project.” Join the community, here.
The reason for the name 3D Printing Party 24 is that it’s held in a 24-hour non-stop format. During this time, attendees are encouraged to present their best works with the chance of winning the II National Prize of 3D Printing.
It is organized by the Abadía Tecnológica company as well as the National Association for Education and the Promotion of Technology (ANEFT). However, to make this possible, they rely on the collaboration of the City Council and the University of Burgos as well as sponsorship from companies such as; Telefónica Foundation, FFF World, SEUR, 3DLac and the company BQ.
Rahima Benhabbour is a woman on an amazing mission. Not only is she a professor at the Eshelman School of Pharmacy University department in Chapel Hill, North Carolina she’s also founder of AnnelleO, a 3D printed intravaginal ring.
Benhabbour’s invention could have a major impact in helping women with a multitude of health issues from trying to get pregnant or avoiding pregnancy to the prevention of HIV and other STIs.
AnnelleO would also be impossible to create without 3D printing. All3DP spoke to Benhabbour to find out more about how exactly she’s creating the rings and the inspiration behind her work:
All3DP: What is AnelleO?
Rahima Benhabbour: AnelleO is a 3D printed intravaginal ring and a platform technology for women’s health indications. To give a bit of background on the name, AnelleO means ring in Italian and the way we market it is, An and a dot then the word “elle” which is her in French then the O becomes the 3D printed ring, so “a ring for her”(An.elle.O).
Currently, AnelleO is focusing on developing a once a month progesterone releasing ring for infertility and assisted reproductive technology or ART. This product would be called AnelleO PRO.
What is the inspiration behind AnelleO?
I had worked for years on developing novel vaginal rings for HIV prevention. I was mainly working with EVA (ethylene vinyl acetate) based rings.
The inspiration came from when I was watching a Ted Talk by Joe DeSimone, who is the CEO of Carbon, the company that owns the CLIP™ technology. While he was giving his Ted Talk, he had a printer on stage that was making a ball with complex geometries at a very fast speed and all that I could think was “oh my gosh, what if you could actually print a ring that has those intricate features in it?”
Now we have so many different avenues to fine tune and control the diffusion of drugs from the ring as opposed to just having a solid ring where drug diffusion is very limited in terms of control.
Currently, the IVR is a one-size-fits-all. We know that women have different anatomies, from being young and adolescent to women who have had multiple children and are towards their thirties or forties. There is definitely a difference in anatomy and having only a one-size-fits-all is not really realistic or fair for women.
Why did you choose to begin with a progesterone ring?
The reason why we chose AnelleO PRO, a progesterone-releasing ring, as our first indication is because there is definitely a need in the US for a once-a-month treatment that can provide the same levels of progesterone as a supplementation for promoting pregnancy and maintaining it.
Currently, the marketed products for ART are limited to vaginal gels or inserts that have to be administered two or three times a day and they’re messy and unpleasant. Or, an injection which is painful and has to be administered daily by a partner. So, really there is no treatment out there that can provide supplementation of progesterone in a sustained fashion. This is where our once a month delivery of progesterone comes in to solve that need.
Who do you hope will benefit from AnelleO?
My heart has always been for the philanthropic side of it, so the non-profit side, and that’s where my passion is still and will always be. My hope is that it would help women in first-world countries to provide a better treatment, but the bigger goal for me personally is to see it help the women that are in most need in Sub-Saharan Africa, South East Asia, and South America, really, but mostly Sub-Saharan Africa where the prevalence of HIV is the highest and where women do not have any means in which they can protect themselves in a female-controlled fashion that is discreet, cost-effective and accessible. For me, if we could make that happen it would be a dream come true.
What stage of development is AnelleO Pro in now? When are you hoping to bring it to market?
AnelleO has received funding from the Kickstart program at UNC to carry out pre-clinical studies. We’ve done quite a few of them and have shown we can actually release progesterone over 30 days in an ordered or sustained fashion.
We can finetune the release of progesterone by changing the design or material that we’re using and the way we put progesterone in the ring.
We’re still at the pre-clinical and development (R&D) stage, we have another one or two years of pre-clinical before we can file anInvestigational New Drug application.
At this stage, AnelleO is a start-up. Because of the nature of the product, we’re going to need the facilities to produce these rings meaning we’ll have to partner with a pharmaceutical company to do all that. It’s a long road, but fun and exciting road to say the least.
How is AnelleO made and what materials do you use?
We have a collaboration with Carbon to use CLIP for the AnelleO 3D printed ring. The current biocompatible resin that we’re using is a silosiloxane-polyurethaneed material which is a Carbon resin.
What are the benefits of using 3D printing for creating AnelleO?
The major benefits are control of drug release kinetics. With injection molded rings, because the design of the ring is limited and because drug release happens by diffusion of the drug from the ring, this leads to over 80% of the drug that’s loaded in the ring not being released within the time frame of the use of the ring. We are able to release 100% of the drug that we are loading in the ring.
Injection molded rings are one size fits. It takes weeks to generate a mold with a different cross-sectional diameter and costs ~$50,000 or more. But, we’re using computer-aided-design (CAD) which takes a few sections to change dimensions from one size to another and we can then use the new CAD to print a ring in a matter of minutes.
When many women see the rings that are currently being developed for HIV prevention, some of the first reactions are “wow, this is too big” and they’re worried about the ring changing their anatomy or “this ring looks too medicinal”. If we can make a ring in different sizes that actually appeal to these women so they’ll want to use it – making it look better by designing it to look less medicinal and more comfortable, I think that would make a huge difference.
The other aspects are accessibility and cost. Current technologies that aspire to produce rings with drugs for HIV prevention and contraception still rely on injection molding and involve multi-step and complex engineering and not really cost-effective.
So, if we can make these rings in a single step and cost-effective process and accessible to the people who need them the most this could make a major impact in the prevention of HIV (STIs) and unintended pregnancy.

To showcase their new flexible filament, 3D printer manufacturer BigRep fabricated a 3D printed airless bicycle tire and took it for a spin on the streets of Berlin.
Summer’s here! It’s time to dust off your trusty bicycle and take it for a spin in the park. But wait, why is the rear tire looking so flat? Hmm, maybe you should take the roller blades instead…
Bicycle punctures are a royal pain, no doubt about it. And they’re also a fact of life for two wheeled transportation. But BigRep, a startup in Berlin that specializes in large format 3D printing, reckons they have a viable solution.
They’ve fabricated a 3D printed airless bicycle tire, and they’ve taken it for a ride on the city streets. The tire looks very similar to the prototypes devised by Michelin and others for the automotive industry. Only it’s been scaled down to fit the rims of a conventional city bike.
The tire is the work of designer Marco Mattia Cristofori, who you can also see taking it for a test ride in the video below:
What’s the Point of a 3D Printed Airless Bicycle Tire?
The beauty of a 3D printed airless bicycle tire is that it can be customized in terms of treads — whether for paths from pavement to mountain trails — and wheel size.
But can you expect to buy one in the not-too-distant future? According to BigRep, the prototype tire is primarily intended to showcase the potential of their new new Pro Flex filament. The material is based on TPU, and its flexible nature makes it perfect for an application like this.
Used in conjunction with a BigRep One, an industrial 3D printer with a square meter build volume, Pro Flex can be used for rapid prototyping of items as diverse as skateboard wheels, sporting shoe shells, and ski tips.
So it’s unlikely that BigRep will be going into the bicycle tire business anytime soon. But they’ve certainly blazed a trail for others to follow in their wake.
Product Designer Marco Mattia Cristofori from BigRep turned to the custom wheel rim for a development challenge, creating a prototype virtually indistinguishable from the real thing.
BigRep, the German mechanical engineering company, is reinventing the wheel, so to speak. Marco Mattia Cristofori, a product designer at the company, wanted to show the viability of the company’s large-format FDM 3D printing technology for industrial use. With this goal in mind, Christofori 3D printed a full-scale custom wheel hub prototype for a car.
In addition to providing a relatable use case for 3D printing in industry, Christofori’s goal was to come up with a striking design. He began by looking at wheel rims and hubcaps for vehicles.
In the US, it’s popular to customize vehicle features. But, it’s expensive and time-consuming to create prototypes of these parts. Cristofori found that with 3D printing, it’s possible to create custom part prototypes quickly and easily. These prototypes can then go under molding and form checks much sooner than normal.
“With 3D printing you can prototype organic forms, like with our Terra chair,” said Cristofori. “It allows you to envision more complex shapes, because you don’t really have any limits.”
Cristofori’s Final 3D Printed Wheel Rim Design
Cristofori’s design has branch-like structures coming from the center of the wheel, providing stability and offering an interesting aesthetic. In doing this, he moved away from having just one layer or line on a wheel rim or hubcap.
Of course, this demonstrates one major benefit of 3D printing – complex geometries are possible – unlike with traditional methods. The wheel was printed on BigRep’s new STUDIO 3D printer using high-temperature-resistant filament PRO HT.
In addition to the stylistic reason of inventive designs, prototyping a wheel rim in such a way brings another benefit. End-use wheel rims must have perfect dimension, so 3D printing can be useful for verifying designs before final production as it’s possible to quickly adjust and change a design to ensure a perfect fit.
“What we’ve developed here is a true-to-life model that can be powder coated,” Cristofori commented, speaking about next steps with the design. “We are planning to Meta-Coat one of them, to see how it looks as a more final product with a highly professional effect.”
Cristofori adds that it’s possible to use the BigRep ONE, with its new Power Extruder to get a similar level of detail. He also recommends printing complex designs with BigRep’s water-soluble support material PVA.
Although Cristofori’s design is not fully functional as a wheel rim, he believes it would be possible to 3D print end-use hubcaps in plastic and coated to achieve a metallic effect.
Are you getting ready to celebrate the Mexican holiday of Cinco de Mayo this weekend? Prep for the festivities, which usually entail endless margaritas, music, and food, with some of these Cinco de Mayo-themed 3D prints!
Today is May 5th, and while that might seem like an ordinary day to a majority of the world, it’s a cause for celebration all across Mexico, as well as in the United States and other countries. The annual holiday commemorates the Mexican Army’s victory over the French Empire in on May 5, 1862, but for many people, it has evolved into a cultural appreciation for the amazing food, drinks, and music that have come out of Mexico.
Regardless of where you and your ancestors come from, there’s no denying that Cinco de Mayo is one of the most fun holidays around, especially if you love Mexican culture and cuisine. Why not use your 3D printer to help prepare you for the long day of margaritas, tacos, nachos, and salsa music? Here are five quick and easy things you can 3D print to make your Cinco de Mayo a special.
As some of these models will come in contact with food, we highly recommend using food-safe filaments when taking on these projects.
Margarita Glass Rim Salter
What is it? Nothing says Cinco de Mayo quite like a chilled margarita with lime in a salt-rimmed glass. This 3D printable glass rim salter can do the job for you. Not only does it have the word “MARGARITAS” embedded on it, but it can also be printed in the colors of the Mexican flag!
What is it? Hailing from Mexico, the sombrero is a wide-brimmed hat that helps shield your face from the sun. Why not 3D print a miniaturized version to keep the sun away from your beer? This 3D printable Sombrero is designed to fit over your bottle and give your beverage a bit of style.
What is it? Everybody loves a good taco, and oftentimes, you’ll find the best ones come from your local taco truck. You can now 3D print your own truck capable of delivering tacos into your very hands. This 3D printable food truck doubles as a taco holder, making it easy to prepare and place your taco down onto the truck’s bed.
What is it? If you’ve never heard of Coronarita, then chances are you’ve never experienced Cinco de Mayo to its fullest. This cocktail mixes Corona beer and the classic margarita, making for a refreshingly twisted beverage for all (adults) to enjoy. With this Coronarita Holder, you can attach it to your margarita glass and hold the Corona in place, making for the ultimate drinking experience.
What is it? The best way to kick off Cinco de Mayo (besides with a Coronarita) is with a nice plate of chips and salsa. Bonus points if those chips are served on the sombrero of a 3D printed Marachi band member. He’s not big enough to hold too many tortilla chips, but what he lacks in size he makes up for with a seriously sweet mustache and guitar.
GE awarded $9 million contract by US Navy to develop framework to rapidly 3D print replacement parts for ships, aircraft, and other critical military assets. The focus of the research is 3D printing with metal.
A team of scientists at GE Global Research, the technology development arm for General Electric, have been awarded a four-year contract worth $9 million by the US Navy. Their task is to develop a process for rapidly 3D printing exact digital models of replacement components — and to 3D print these parts in metal.
The team is working together with scientists and engineers from GE Aviation, GE Additive, Honeywell, Penn State, Lawrence Livermore National Laboratory (LLNL), Navy Nuclear Lab (NNL) and the National Center for Defense Manufacturing and Machining (NCDMM).
The approach is to build “digital twins” from model-based data on parts and sensor-based data from 3D metal printers to dramatically speed up the qualification and certification process. This applies both to replicating and printing replacement parts no longer manufactured for various naval marine and aviation assets, and to create parts for newly designed assets.
GE Digital Twins are described as living, learning digital models of physical assets, parts, processes and even systems. These models are continually updated as new sensor data or engineering knowledge from technical experts is integrated to reflect the exact state of its physical counterpart at any point in time.
“Using GE’s Digital Twin technology, we’re aiming to rapidly speed up the time that parts could be re-engineered or newly created using 3D printing processes,” says Ade Makinde, Principal Engineer, Additive Technologies at GE Global Research.
“With today’s technology, the process for designing a new part can take years. We think we can reduce that timeframe to weeks, with the unique digital solutions under development.”
Makinde explains that it is extremely difficult to quickly make a 1:1 replacement part through 3D printing processes that was originally produced using conventional manufacturing techniques.
“The key challenge with industrial 3D printing is being able to additively build a part that mirrors the exact material composition and properties of the original part that was formed through subtractive measures. With the kind of mission-critical equipment the Navy operates, there is no room for deviations in material performance or manufacturing error.”
US Navy Banking on Digital Twins to Stay in Ship-Shape
Having a rapid process for producing and installing replacement parts would greatly support the US Navy’s efforts to manage and maintain excellence for an aging Navy fleet.
The average age of active Navy ships, for example, is 17 years. The oldest in service was deployed in 1970. In cases where ships are several decades old, replacement parts often are no longer manufactured.
This is similar to what car enthusiasts have experienced when rebuilding or repairing classic or older cars. Just like the automotive sector, the Navy is turning to 3D printing to get the parts they need faster.
“We’re already seeing the proliferation of 3D printing in the automotive sector, which are enabling the manufacture of outdated car parts no longer being made,” said Makinde.
“When it comes to mission-critical assets like Naval ships and aircraft, the bar is higher for producing high quality parts that encounter much higher stresses and tolerances. But as one of the world’s leading aircraft engine makers that produce and maintain a fleet of 35,000+ jet engines that are in service for decades, we bring a unique understanding and depth of expertise to what kind of digital models are required.”
The four- year program will occur in a pair of two-year phases. Phase 1 will focus on the underlying software and hardware developments. In Phase 2, GE will build a complete additive system that demonstrates the rapid and robust creation of a part’s digital model or digital twin and printing of that part using a 3D Direct Metal Laser Melting (DMLM) printer.
Mindkits is a “family run and kiwi-owned” tech company whose latest project brings extinct New Zealand moa bones to classrooms via 3D scanning. With models of the bones in hand, teachers and students can prep and print them in full size.
The extinct New Zealand moa was an interesting bird. Flightless and looking a lot like the modern day ostrich, it could grow to 3.6 m (12 ft) in height and weighed about 230 kg (510 lb).
Rather than learning about these creatures from textbooks, MindKits, an Auckland-based tech company, is giving schools the chance to learn about the magnitude of the bird from accurate 3D printed bones.
The moa bone project was created to take bones from behind the glass of museums and make them more accessible for teachers to use. With the help of 3D scanning and printing, the original bones can remain safely on display, with exact 3D printed replicas giving children a tactile learning experience.
Tim Carr, MindKits founder, hopes the project will be used in a range of subjects while also inspiring discovery and exploration in students. He adds: “We’re smashing together technology and ecology in the most hands on way possible – using 3D scanning and 3D printing to recreate the rich natural history of New Zealand“.
Meticulously 3D Scanning an Ancient Bird Bone
Procuring and printing the moa bones was no easy feat. The leg bone alone took MindKits 102 hours to print. However, this wasn’t the most difficult aspect of the project. Carr explains that he had the idea of scanning and printing the moa bones for educational use back in 2014.
But, museums which hold the moa remains were very reluctant to allow access to the bones. Thankfully, the project was revived due to a chance meeting with Wellington based teacher, Tony Cairns, whose family has a private collection of moa bones.
Cairns decided to loan MindKits the bones, which were recovered from Wairarapa farmland in the mid 1970’s. The most impressive bone has to be the longest, which is the tibiotarsus leg bone measuring at 85cm.
The MindKits team then meticulously 3D scanned the ancient bones. So far, 120 3D specimen packs have made it to schools. The project will run from April until June.
To apply to receive a project pack, visit the MindKits website and submit your email address. If you match the criteria, you’ll be sent a Giant New Zealand Moa Discovery Pack which includes class information and a USB stick with everything you need to get started.

A 3D printed Death Star in its original size and glory – that’s a 3D printing project of galactic proportions. Franklin Houser has crunched the numbers.
So, what does it take to 3D print a 1:1 scale Death Star? The question I have asked myself depends on several variables. For simplicity, I will only be focusing on material costs, and the time needed to complete the task as well as a few different scenarios. One crucial factor is the ratio between the solid material and open space within the battle station as we would only 3D print the solid components.
Get Prepared for a Big Shipment of Filament
A good comparison would be a skyscraper. The Burj Khalifa in Dubai is currently the tallest man-made structure in the world. A large front lobby and 57 elevator shafts make for a good representation of hangar bays and reactor shafts in the Death Star. I did some quick research and found out that the Burj Khalifa has a volume of roughly 2,600,000 m3 based on the total accumulative surface area per individual storey and its height. Considering that the skyscraper was constructed using reinforced concrete at 2400 kg/m3 on average, and has a total empty weight of 440000 metric tons, the building consists of roughly 10% solid building materials and 90% air-filled space. Surprisingly enough, if you were to 3D print a solid 1:1 scale replica of the Burj Khalifa out of classic ABS filament, it would be heavier than the real thing.
Now let’s assume that 10% of the 3d printed Death Star’s volume was also comprised of solid building material.
According to Wookieepedia, the first Death Star was a spheroid with length, width, and height measuring 120 km making it as good as completely spherical. Excluding the fact that there is a conical indent on its surface for the super laser, capable of destroying entire planets, the volume of the first Death Star came to roughly 905,000 km3. That’s a lot more than the Burj Khalifa. That means that the total solid volume of the Death Star was 90,500 km3.
Using ABS filament, which has a density of 1.08 g/cm3 on average, we would need 97,740,000,000,000,000 kg of it. That’s ninety-seven quadrillion, seven hundred forty trillion kilograms.
How Long Does it Take to 3D Print a Death Star?
Most 3D printers can print at a speed of 24 mm/s at least. At that rate, it would take a little more than 119,572,000,000,000 years to complete the 3D printed Death Star. We might as well watch the universe grow cold while we’re waiting for our Death Star to become fully armed and operational. The amount of filament needed would currently cost 3,323,000,000,000,000,000 Euros if bought in 0.75 kg spools with no discount.
Those numbers are extremely huge, and realistically, the task would never be possible using a desktop 3D printer, unless it could print at a speed of 143487 m3/s at which rate our 3d printed Death Star would be finished in 20 years. That’s how long it took the Galactic Empire to build the first one.
ABS or PLA for a 3D Printed Death Star?
There are however a few more factors to consider when planning to 3D print a Death Star. For one, we would have to construct a mechanism to move the printer along the surface of what has already been printed, since the entire Death Star would not fit inside the tiny box of a desktop 3D printer. And, the entire construction would have to take place in space, since it would be extremely difficult to blast the finished Death Star into earth’s orbit.
Secondly, we would need some power supply; probably solar power. Lastly, ABS filament starts to get soft around 105°C and melts at under 300°C. If the Death Star got anywhere near a star during its lifetime, it would simply turn into a giant ball of molten ABS or burn up. There are many more factors that would restrict the construction of such a Death Star with today’s technology.
Conclusion: Is it Worth it?
If you had the time and the money, then definitely; because who wouldn’t want to cruise around the galaxy in their very own Death Star? I can think of one advantage that would come of the extremely long print time. If kept in complete secrecy, the duration of the build might just outlast the existence of the Rebel Alliance or The Resistance, thereby greatly increasing the chances of it ever aging or even being completed.
Over on Amazon.com, select colors of 2.85mm colorFabb nGen filament can be had for silly prices compared to their usual premium.
A hardy filament billed as an all-rounder for everyday 3D printing use, colorFabb’s nGen is a popular choice for ease of printing and vibrant colors. There’s no denying it’s not your run-of-the-mill budget filament though, which makes the price we’ve found some selling at all the more special.

An ambitious new collaboration between We the Builders and Adam Savage seeks to crowd-source and 3D print a six foot tall sculpture of Rosie the Riveter for the Nation of Makers Conference in June.
The concept of We the Builders is simple to the point of genius. They assemble large sculptures of historical figures like Benjamin Franklin, George Washington and Edgar Allen Poe. But instead of carving from stone or casting in bronze, each sculpture is assembled from hundreds and thousands of 3D printed parts, crowd-sourced from volunteers located all over the world.
This year’s project — their fifth — is their biggest and most ambitious yet. To celebrate the contributions and diverse identities of women and non-binary makers, they’re scaling up a sculpture of WWII cultural icon Rosie the Riveter to monument-size.
The sculpture is the handiwork of artist Jen Schachter, who sculpted the a 7″ tall Rosie bust in oil-based clay over a wire armature. After completion, it was 3D scanned, digitally scaled up, and sliced into printable pieces.
If the project is successful, this very special Rosie the Riveter will be over six feet tall and made up of 2,625 parts. But to get there, they need the support of everyone in the maker community — regardless of their gender identity — to help 3D print it.
The grand unveiling of the sculpture will take place during NOMCON in Santa Fe, New Mexico, in June. NOMCOM is a gathering of makers hackers, and technologists hosted by Nation of Makers. Here’s the pitch video from Adam Savage of TESTED fame.
Rosie the Riveter Says: “We Can 3D Print It!”
Interested in taking part? You can claim your segment of the model by signing in with a Google account and clicking on “Give me a File to Print”. We the Builders are keen to emphasize that all parts should be made in skin-tone colors. This is to celebrate the diversity of identities of today’s makers.
The material doesn’t have so strict a requirement, however. Past projects have included parts made from ABS, PLA, PHA, wood, resin, metal plated, glow-in-the-dark, and more.
After fabrication, participants should send a photo of their part and then ship it back to We the Builders. Full details can be found on their how it works page.
Several filament manufacturers are also offering discounts to support the project. MatterHackers is offering 5% off everything (excluding Ultimaker merchandise). Follow this link and enter ROSIETHEHACKER at checkout. Elsewhere, DeltaMaker is offering $9 off brown, gold (tan), and natural filament. Use code ROSIE at checkout.
Finally, We the Builders stress that time is of the essence. They only have 3 weeks to collect all the parts. If you don’t post your piece within a few days of claiming it, it will be released so someone else can make it.
For those folks without access to a 3D printer, there are other ways to participate. These include hosting printing parties, video documentation, or a good old fashioned cash donation via PayPal. Check out the official project page for the full details.
GM is using Autodesk’s generative design technology and additive manufacturing to fabricate lighter automotive parts; this seat bracket is 40% lighter and 20% stronger than its predecessor.
General Motors is using generative design software by Autodesk to develop the next generation of lightweight vehicles. According to the automaker, the new technology will be a key factor in developing more efficient, alternative-fuel cars with zero emissions.
GM is the first automaker in North America to use the software. It uses cloud computing and AI-based algorithms to rapidly explore multiple permutations of a part design; it can generate hundreds of high-performance, often organic-looking geometric design options based on goals and parameters set by the user.
These parameters can include weight, strength, material choice, fabrication method, and more. Once generated, the user can then select and 3D print the best option from the available part designs.
“This disruptive technology provides tremendous advancements in how we can design and develop components for our future vehicles to make them lighter and more efficient,” says GM Vice President Ken Kelzer, Global Vehicle Components and Subsystems.
“When we pair the design technology with manufacturing advancements such as 3D printing, our approach to vehicle development is completely transformed and is fundamentally different to co-create with the computer in ways we simply couldn’t have imagined before.”
The new design technology provides significantly more vehicle mass reduction and parts consolidation, the likes of which cannot be achieved through traditional design optimization.
GM and Autodesk engineers have applied this new technology to produce a proof-of-concept part. They’ve demonstrated a new seat bracket that is 40 percent lighter and 20 percent stronger than the original part. It also consolidates eight different components into one 3D printed part.
GM and Autodesk Entering Multi-year Alliance
GM has been a leading innovator in additive manufacturing for more than three decades. The automaker has one of the auto industry’s most comprehensive 3D printing capabilities in the world, with more than 50 rapid prototyping machines that have produced more than 250,000 prototype parts over the last decade.
Looking to the future in a multi-year alliance, GM and Autodesk will be collaborating on projects involving generative design, additive manufacturing, and materials science. Executives and engineers from both companies will participate in a series of onsite engagements to exchange ideas, learnings, and expertise.
“Generative design is the future of manufacturing, and GM is a pioneer in using it to lightweight their future vehicles,” says Scott Reese, Autodesk Senior Vice President for Manufacturing and Construction Products.
“Generative technologies fundamentally change how engineering work is done because the manufacturing process is built into design options from the start. GM engineers will be able to explore hundreds of ready-to-be-manufactured, high-performance design options faster than they were able to validate a single design the old way.”
Eliminating mass in parts where material is not required for performance — combined with parts consolidation — will bring many benefits for car owners. This includes the potential for more interior space, increased range, and enhanced vehicle performance. It also provides vehicle designers a canvas on which to explore designs and shapes like never before.
For this week’s Project of the Week, 3D print and Arduino your way to this coin-spitting Question Block from universe of Nintendo favorite, Mario.
Loose change, shrapnel… whatever you call it, the blight of small denomination coins deserves better than sitting in a jar on the shelf at home. Which is perhaps the thought that crossed maker Jonathan Whalen’s mind when he created a fully functioning Question Block from the Mario universe.
Putting his spare change to use in some video game themed frivolity, he fashioned a Question Block from the Nintendo’s Mario video game series using a 3D printer, Arduino and a bunch of other small electronics parts.
The result is pretty spectacular. We’re just holding out for the mushroom-ejecting remix.
Find out how to build your own after the jump.
Super Mario Question Block: What do You Need?
In order to create your own Super Mario Question Block, you’ll first need to download and print the required STL files. Handily Whalen has published them on the usual file repositories — you can get them from Thingiverse here.
Naturally you’ll need to print the main sections of the box in that signature yellow color too, which means an appropriately hued filament. That, and white for the question mark symbols themselves.
It’s also worth keeping in mind that the box will only shoot $1 coins. Whalen provides an STL to print your own correctly sized coins, which would naturally look best printed in gold filament.
Here’s the full bill of other materials you’ll need:
Super Mario Question Block: Putting it all Together
To create this coin-shooting Question Block, Whalen (a.k.a. Jonnywayway) 3D prints the outer shell, glue-on question marks and structure of the internal coin-firing mechanism. Printed at 20% infill with no supports, Whalen describes it as a long print, so leave yourself adequate time if you’re planning to whip this up to a deadline.
The mechanism to spit the coins out of the box is ingenious for its simplicity. A sliding carriage slots into a guiding rail printed in place on the “roof” part of the box. Held in place with a rubber band, this carriage is free to slide deeper into the box, bringing a coin with it, before firing back into place under the elastic tension from the band.
With the band and carriage in place, Whalen fixes the Arduino Nano, vibration sensor and slide switch in place (also on the roof of the box) with screws, before turning his attention to the stepper motor.
Inserted into one of the printed pieces for the mechanism, the motor mounts to the guiding rail. With a printed cog attached to its driveshaft, the stepper draws the carriage down, releasing it to spring back into place and launching a coin in the process.
Wiring these electrical components up, then its just a case of closing the box and gluing the decorative elements on the outside.
It’s worth noting this’ll be a tough project for absolute beginners. Whaley linking to the Arduino code but does not going as far as to explain how to set it all up. The same goes for hooking up power inside the Question Block. Though we imagine carefully watching his build video should give some clues.
To celebrate its first VR Google Doodle, the internet giant dreams big with a charming animation charting illusionist and film director Georges Méliès, creator of early cinema classic Le Voyage dans la Lune.
Spicing up the search giant’s homepage since 1998, the Google Doodle has become something of a pop culture mainstay. Be it an educational animation or addictive mini-game, it has been a welcome bonus to our everyday searchings.
Today, Thursday May 3rd, Google has taken a departure from past Google Doodles with its very first VR adventure. And it’s a doozy.
The result of a collaboration between the Google Doodle, Google Arts & Culture and Google Spotlight Stories teams, plus The Cinematheque Francaise, today’s Doodle is a visual feast exploring the work of French cinema pioneer Georges Méliès, who is perhaps best known for Le Voyage dans la Lune (A Trip to the Moon).
The Doodle, in the form of an interactive 360 degree Youtube video for those of us viewing in a browser, is available as a dedicated app for iOS and Anroid, and best enjoying through a VR headset such as Google’s Daydream or other 3rd party devices. Check it out in full below, and don’t forget to full screen it and click about to get the full effect.
Part of a larger effort on behalf of Google’s cultural teams, an in-depth (and utterly fascinating) online-exhibition charting Méliès life and work can be found on the Google Arts & Culture website. Also, if you’re looking for the ultimate time killer, here’s the Doodles Archive — something we never knew existed until now. You’re welcome.
Audi is pairing up with EOS who will implement modern 3D printing technology into automobile manufacturing. However, the German car manufacturer is also working with SLM and using their selective laser melting processes.
Over the course of 30 years, 3D printing has proven itself as a useful technology in the development of automobiles, as coverage on All3DP proves. Now Audi AG, the German automobile manufacturer, is expanding its 3D printing efforts to incorporate the technology even further.
Previously, Audi has used 3D printing for its motorsports division, creating equipment and building prototypes. But, to make sure they’re getting the most out of the technology, Audi has launched a development partnership with EOS, the additive manufacturing specialist.
EOS Additive Minds consulting division will work with Audi to implement 3D printing into its production. However, they’ll also be on hand to help with the development of a 3D printing center in Ingolstadt, Germany.
“The aim is to not only supply Audi with the right additive systems and processes but to also support them during applications development, when building up internal additive manufacturing (AM) knowledge and training their engineers to become in-house AM experts,” said Güngör Kara, Director of Global Application and Consulting at EOS.
However, EOS isn’t the only company working with Audi. SLM Solutions Group AG will also be collaborating with Audi who will be using their selective laser melting process. The technology will enable Audi to supply spare parts on demand.
Producing Audi Parts in an On-Demand and Cost-Effective Manner
Audi explains that the reason for setting up the competence center is to learn more about 3D printing and gain experience with the processes and materials. Therefore, pairing with EOS was essential as they can provide guidance and support.
“With this technology, we are able to integrate internal structures and functions in tools that we have not been able to create so far with conventional manufacturing methods. Especially with components in small batches, we can now produce components using lightweight construction, quickly and economically based on this technology,” explains Jörg Spindler, head of Toolmaking at Audi.
An important vision for Audi to achieve is being able to manufacture on demand, supplying spare or complex parts which aren’t regularly required but are important nonetheless. By using 3D printing, they’re saving money and time, but also using a more sustainable technology.
“The new constructive freedoms provided by this technology are especially interesting… Components for prototypes and spare parts requested extremely rarely are better suited for SLM processes than conventional manufacturing procedures thanks to the benefits of free geometric design. The load capacity of the components is comparable with parts manufactured using traditional methods,” said Harald Eibisch, who works in the technology development department at Audi.
The Anycubic i3 Mega is already good value for money, but for a limited time today that goes doubly so as Amazon.com sees a Lightning Deal reduction of $55.50 from this 3D printer’s usual retail price.
The Anycubic i3 Mega is a pretty snazzy 3D printer, combining unique looks and novel features with an affordable price tag. Now that price has stooped a little lower with this limited time Lightning Deal on Amazon.com.
Ordinarily priced at $368.99 on the US retail giant, at the time of publishing the Anycubic i3 Mega can be picked up for $313.49. Amazon Prime members can access the deal early, from 1pm CET. All the non-Prime folk out there will have to wait until 1.30pm CET to pick one up at the special price.
Packing a 210 x 210 x 205mm print area atop an Ultrabase print bed, filament run out detection, simple assembly (from two main parts) and a large easy to navigate touchscreen interface, we found the i3 Mega to be a pretty amiable 3D printer.
Not without its quirks and small issues, for the price it’s excellent value for the consistent quality it can output.

Among the multitude of Rapid + TCT announcements, Stratasys showed off the impressive capabilities of its upgraded J750 PolyJet 3D printer alongside the brand new J735. Both can print over 500,000 color combinations in addition to textures and transparent parts — all in the same print.
It’s May now, but we still want to talk about April’s Rapid + TCT show. Such is the indelible mark the event leaves on the 3D printing industry, with big names making bigger announcements.
One such big fish is Stratasys, which took the opportunity to show off its upgraded J750 3D printer. Using PolyJet 3D printing tech, the machine is positioned as the company’s top-spec multi-material, multi-color production 3D printer.
Via a new color pack offering for the printer, Stratasys allows for what it claims is highly accurate color matching. In short, the ability to take photo realistic models and render them virtually perfectly in physical form from over 500,000 colors.
This is possible due the to software and printer’s control of the print at the voxel level. Granting control of a print (volumetric) pixel by pixel, advanced results that leverage 6 materials when printing means nigh product worthy prototypes (within a single print) are a reality.
Thanks to the company’s GrabCAD Print software (which has also gotten some love lately, with operability with the Connex3 printer added), this advancement expands further to improving and simplifying the design-to-print workflow.
Statasys Ups Its Game for Realistic Prototypes
Coinciding with this betterment of the J750 printer, Stratasys also announced an all new machine in the J735. The new J735 is fundamentally the same as the J750, but offers a narrowing of the build size, at 350 x 350 x 200mm compared to the J750’s 490 x 390 x 200mm.
That, and two new materials offering better representations of yellow to red colors, including tinted translucency such as one might find on car light housings, were revealed. This is especially pertinent for the automotive industry, one increasingly looking to AM for parts and models during the design process.
In a release from Stratasys, Reinhard Schiechel & Dr. Tim Spiering of Audi’s Model shop and 3D printing center said “we are able to produce prototypes with incredible realism, such as the transparent multi-color covers for our tail lights. This can offer the texture and color-matching requirements to meet our design approval process,“.
Rich Garrity, President Americas of Stratasys continues in the same release: “Some of the biggest challenges designers and manufacturers face are 3D printed prototypes that fail to deliver the realism necessary to make them actionable.“. In the upgraded J750 and new J735, the company hopes it offers the solution.
During work hours, Matt Denton is director of visual effects company Micromagic Systems – known for stunning Harry Potter and Star Wars effects. In his spare time, he publishes videos on his YouTube channel Mantis Hacks. But, as a maker, he’s not content with leaving it at that – instead, he 3D prints Lego kits and makes them much bigger. He then assembles them with his nephew, and hilarity ensues.
Matt Denton and his young nephew are at it again. Previously, Mr. Denton designed and 3D printed a giant lego go-kart and built it, while his nephew built the regular size kit, which All3DP reported on at the time.
Since then, he’s had many other large 3D printing projects including a giant lego forklift to go with his go-kart. He based his design on the LEGO Forklift from 1977. It took over 500 hours to print 215 pieces.
Now, his latest 3D printed kit got even bigger. This time around, he created the Lego Bulldozer from 1979. This design took 600 hours of printing to create the necessary 372 pieces.
Reuben, Denton’s nephew, is a great sport and yet again helps Denton build his oversized Lego kit:
How to 3D Print a Giant Lego Bulldozer
If you feel your 3D printer is capable of creating giant Lego prints, Denton has made his 3D files available on Thingiverse. However, he asks that to help him continue with his projects, anyone who downloads them leaves a tip.
For this project, Denton used a Lulzbot Taz6 3D Printer, a Taz5 3D Printer, and a Lulzbot Mini Printer. The filament for his project came from 3Dfilaprint. He used Premium PLA.
Although Denton has yet to do a follow-up video for his Giant Lego Bulldozer, check out his previous explanation video for the giant forklift to learn more about how he creates such large prints.
You can follow along with Denton’s Giant Lego projects easily with his series on YouTube. Don’t forget to subscribe, as he also has some other fantastic projects which don’t involve huge Lego parts. For example, Denton adds: “Hexapod walking robots, electronics, hacking, coding, engineering, 3D printing and other stuff.”
Held together with 3D printed joints and utilizing high-tech The Breath fabric, Japanese architect Kengo Kuma’s “breath/ng” sculpture looks good and does good.
Standing at an impressive 6 meters tall, renowned Japanese architect Kengo Kuma‘s breath/ng origami-like sculpture captures the imagination as much as it does pollution in the air.
Designed for Dassault Systèmes’ Design in the Age of Experience exhibition at Milan Design Week in April, Kuma’s sculpture is a snaking, winding vessel of hand-folded The Breath panels, making use of 120 panels totaling out to 175 square meters of material.
No ordinary art piece, Kuma’s breath/ng serves a practical purpose, in that is can absorb airborne volatile organic compounds (VOCs) and other airborne nasties directly from the air, disaggregating them in the process.
Dassault Systèmes tasked Kuma with finding a solution to a modern (and growing) problem using today’s tech for its Design for Life sub-exhibit.
Suspended from the ceiling by a single carbon fiber rod, the concertina-like form of breath/ng is fixed in place by 46 3D printed joints.
As a part of the exhibition, Kuma took to the stage to deliver a keynote speech alongside CATIA Dassault Systèmes CEO Philippe Laufer. An open invitation to designers to consider such pollution-fighting materials as The Breath, Kuma’s sculpture also leveraged Dassault Systèmes’ suite of 3D modeling and design software for its creation.
In addition to mapping out his vision of a soft material based structure, Kuma’s design process resulted in the use of HP Multi Jet Fusion 3D printing to produce 46 unique joint pieces. These pieces are used together to maintain the structure and rigidity of breath/ng.
Developed with and for teachers, 3Doodler has unveiled learning packs for the classroom. Included in the packs are 12 3Doodler 3D pens, 1,200 strands of filament and lesson plans, which the company claims can improve concentration among students.
3Doodler, the company behind what is though to be the world’s first 3D printing pen, is releasing a new educational product line for classrooms. The company has worked with teachers to develop tools and lesson plans enhanced by its 3D printing pen.
Available in two versions — 3Doodler Create+ EDU Learning and 3Doodler Start EDU Learning — the new products will be available through the company’s website and major retailers.
Both of the packs feature 12 3Doodler (Create+ or Start, depending on the pack) pens, 1,200 strands of filament and accessories for maintaining the pens. That, and the requisite curriculum materials to make the most of the 3D pens, providing a fun and tactile entry point to STEM subjects. Smaller sample packs are also available.
The key difference between the two packs lies in the pens included. 3Doodler’s Start pen features is the more child-friendly of the two, with no hot parts (the company recommends the Start pack for ages 6 – 13). Meanwhile the Create+ pen, while still child-safe and recommended for ages 14 and up, does heat up.
“These products represent 3Doodler’s continued commitment to inspire students pursuing STEM interests and passions,” said Leah Wyman, 3Doodler’s Head of EDU. “We pride ourselves on creating accessible 3D products and making it fun to learn in the classroom.”
Can 3D Printing Pens Really Improve Concentration Among Kids?
3Doodler believes that children will hugely benefit from the kits. Already they’ve made it into schools with products reaching some 5,000 classrooms and into the hands of more than 300,000 students.
The company claims that through numerous case studies, they’ve found that the kits stimulate kinesthetic and visual learners. Better yet, they also improve concentration among the students, including those with ADHD. Indeed there appears to be some backing for the company’s claims, with Kokoa — a European agency that evaluates educational technology — recommending the company’s new EDU packs.
3Doodler add that the kits help diversify teaching methods meaning students are more incentivized. With such huge promises from 3Doodler, it’ll be interesting to see whether teachers do feel these benefits.
The learning packs are available from the likes of Amazon and Best Buy, plus the company’s official website. Prices will range from $347 to $1,199.
Mark Rehorst is a blogger detailing his technical projects. For his latest post, he worked on creating an easy to produce blower for a remote cooling fan. For this, he turned to a hard disk drive motor and a few 3D printed parts.
Blogger Mark Rehorst has spent a long time finding the perfect 3D printer cooling fan. He explains that a couple of years ago he began trying to build a large-scale chocolate 3D printer.
For this project, he wanted to use a remote cooling fan. He explains that for his 3D printer, he wants to move the cooling fan off the print head and route a flexible tube instead. A heavy cooling fan on the tip of the extruder can cause drooping and warping – this isn’t the case with a lightweight tube.
To do this, he tried out a few different fans, which can be read about in his last blog post, The Mother of All Print Cooling Fans. The fan he finally settled on was one he took from a machine used to help people combat sleep apnea – the CPAP machine. He found this fan in the parts bin in Milwaukee Makerspace.
However, although it works well, it does move more air than necessary. The other negative is also that these parts are very hard to come by or expensive.
So, he took to the depths of a RepRap forum to find an alternative answer. What he came up with was very interesting – he decided to test out a 3D printed impeller and housing. To complete the blower, he used a hard drive motor to make it spin.
“I decided to try my hand at designing a printed blower that would mimic the function if not the performance of the CPAP blower,” he explains. In the video below, you can see the result of his proof-of-concept.
Pick up a Hard Disk Drive from a Friend’s House & Get to Work
The hard drive certainly provides a cheap and easy to source solution to Rehorst’s CPAP problem. He explains: “The heart of the blower is a hard disk drive motor which most people can pull out of an old drive for free. If you don’t have one, someone you know does.”
To create the proof-of-concept blower, he first picked up a hard drive from his local makerspace. Then, he took measurements and created a model for the motor. Next, he did the same for the impeller and finally the housing.
Although Rehorst did a great job in creating the resulting 3D printed blower, he adds that the next phase is to add the CPAP hose and experiment with a design where the exit port will be on the base of the housing which he adds will be easier to print.

Save the planet and print using hemp: 3Dfuel is now offering a new, improved Entwined hemp filament with some “pretty big” changes from their v1 first release of the material.
Although we believe 3D printing could save our environment by reducing waste and speeding up manufacturing processes, there is yet some way to go to produce a popular filament for hobbyists which is good for the planet too.
However, 3D printing filament company 3Dfuel is working on creating specialized 3D printing filaments which have a focus on sustainability and eco-friendliness.
So far, they’ve launched Wound Up, a filament made from coffee, and Buzzed, a filament made from beer. Last year, 3Dfuel also launched Entwined, an eco-friendly filament based on hemp. They claimed it’s the first commercially available hemp filament in the world. And no, it does not contain the typical byproducts of cannabis sativa, so inhaling any fumes will not make you run to the fridge in search for food.
3Dfuel improved upon their filament and are offering Hemp Filament v2 which offers some “pretty big changes”. A 500g spool will set you back €43 excluding VAT.
Improvements to Entwined
The company explains that changes to their most popular composite material include, reducing the particle size of the hemp material while increasing the percentage of hemp material. They add: “If you had a tricky time printing with Entwined in the past, the new formulation is much better.”
They’re also making it possible to print using a wider variety of 3D printers and nozzle sizes. Supposedly, this leads to a more consistent and slightly different print finish that Entwined version 1. Although the filament promises characteristics similar to that of PLA, it is unclear how durable Entwined really is.
Remember, to print with Entwined, you should start at 10 degrees cooler than you typically print with PLA. It prints best between 180-210 C and with a print bed set at 45 C – although a heated print bed is not necessary.
Using this filament will result in a brown print as Entwined doesn’t contain any dyes, meaning it keeps its natural color. However, reviews on their product page have been great so far, the wow-factor of the filament outweighs the dull color.
Other companies carrying filament made from hemp include Hemp Dispensary. Their product is yellow; a 2.85mm 3D filament of 500 grams costing €29.
