    There’s no need to buy an electric screwdriver, just 3D print your own!

    Arduino Team — December 11th, 2018

    What do you do when you need to attach 400-500 screws for an upcoming project? If you’re “Progress Thailand” you simply create one yourself using a 9g micro servo modded for continuous rotation, an Arduino Nano, and some 3D printing!

    The build uses a small thumb joystick for proportional control, and can accommodate a small hand driver in addition to a bit by itself. Impressively, a functional prototype of the tool was produced in a single day, with the final(?) version appearing a couple of days later. 

    Hand and power tools are cheap, reliable, and easily accessible. But their production is still done in large centralized factories. 3D printing technology and cheap, open source electronics continue to improve bringing the decentralization of manufacturing one step closer.

    We are experimenting with different designs to see how close current 3D printing technology can bring us to production-quality tools you can buy in the store. We’re also experimenting to see what modifications we can make to store-bought tools to enhance and customize their use.

    While they note that the project isn’t meant to replace commercial screwdrivers at this point, it looks like a fun project with all the needed files available here to modify and improve things to your specifications!

  • Convert a Dremel tool into an Arduino-controlled CNC machine

    Convert a Dremel tool into an Arduino-controlled CNC machine

    Arduino Team — November 26th, 2018

    3D printers get most of the attention in maker-fabrication news, but other computerized tools, like laser cutters and CNC routers, can also be extremely useful. In fact, Nikodem Bartnik decided to create his own Dremel-based machine constructed out of 3D-printed parts and aluminum profiles. 

    Electronics include an Arduino Uno and CNC stepper shield running GRBL for control, along with some NEMA 17 steppers and motor drivers, a relay for the Dremel, and a 12V / 30A power supply.

    As with many other projects, his build went through several iterations, but the final results—seen in the video below—are quite good. The machine, which only cost him around $300, is able to mill MDF and acrylic.

    If you’d like to make your own, Bartnik outlines his design in the first video below, then shows how to use it in the second.

  • This 3D Printed Robot Can Crawl Underneath Doors

    This 3D Printed Robot Can Crawl Underneath Doors

    Reading Time: 2 minutes

    A designer has developed a 3D printed robot that can auto-adjust its height to maneuver a wide range of spaces.

    A Reddit member called potentprintables has just presented a 3D printed robot that adjusts its size in order to fit into tight spaces. That means the robot can also squeeze underneath doors.

    It’s really rather remarkable to watch the Minority Report inspired creation crawl across the floor and adjust its size as it hits an obstacle.

    The user says that the robot is actually based on the design by David Zarrouk, Andrew Pullin, Nick Kohut and Ronald Fearing at the Biomimetic Millisystems Lab, UC Berkeley.

    Inspired by Nature

    The original six-legged, sprawl-tuned autonomous robot (STAR) is able to adapt its leg-to-surface contact angles. According to the accompanying research paper, the Zarrouk team drew their inspiration from insects. Specifically, they focused on the crawling motion of the robot.

    Furthermore, the STAR device was developed with easy recreation in mind. It has been 3D printed using a Project 3000 machine.

    Potentprintables’ version of the device expands on the original concept.

    The user also shared full instructions and a bill of materials needed to allow other experienced 3D creators to have a go. Although easy to print, he warns that the mechanics necessary to finish the project aren’t for beginners.

    Take a look here.

  • Stelia Aerospace Demos Cheap, Light and Strong Aircraft Fuselage Using WAAM

    Stelia Aerospace Demos Cheap, Light and Strong Aircraft Fuselage Using WAAM

    Reading Time: 3 minutes

    French firm Stelia Aerospace has lifted the lid on its newest innovation. Using WAAM (wire arc additive manufacturing), the company has demonstrated metallic self-reinforced aircraft fuselage panels that cut costs and save time from the assembly process.

    Aircraft structures and seating are the bread and butter of Stelia Aerospace’s business, with its designs and processes in place in products by the likes of Airbus and Boeing. So it stands to reason that the manufacturer would look to innovative ways to optimize it’s work. Showcasing the tremendous potential of additive manufacturing, the company recently launched its first self-reinforcing fuselage panel, which makes use of WAAM (wire arc additive manufacturing) for its construction.

    Constructed as part of the DEveloppement de la Fabrication Additive pour Composant TOpologique (DEFACTO) project — a research strategy founded by the company in 2014 to explore additive manufacturing in its particular field of fuselages and large aircraft sub-assemblies — the 1 sq m panel emphasizes that large-scale 3D printing in aerospace design is possible.

    Traditionally the types of panels the firm looks to produce are a skin of aluminum stiffened with a skeleton of supports that are manually attached. However, an issue with this is that each and every element requires meticulous placing, fitting and eventually welding together. This is a costly process that requires significant time.

    By using WAAM to reinforce the panels instead, the company finds that the resulting panel is not only lighter, but cheaper to produce too. Put simply, WAAM utilized a robotic arm to weld metal material (in the form of a wire) in successive layers, much like fused deposition modelling.

    “With this 3D additive manufacturing demonstrator, Stelia Aerospace aims to provide its customers with innovative designs on very large structural parts derived from new calculation methods,” explained CEO of Stelia Aerospace, Cédric Gautier. “Through its R&T department, and thanks to its partners, Stelia Aerospace is therefore preparing the future of aeronautics, with a view to develop technologies that are always more innovative and will directly impact our core business, aerostructures.”

    As a bonus, the process is more environmentally friendly as it integrates multiple functions into a single part and generally requires less material.
