    Arevo Boosts Expansion of Carbon Fiber 3D Printing With $12.5 Million Funding Round

    The start-up has launched a unique carbon fiber 3D printing technology that allows for enhanced scalability. Through the latest cash injection, it hopes to commercialize the technology more quickly.

    Carbon fiber 3D printing is set to become a dominant trend in additive manufacturing over the next few years. This is driven in part due to the material’s incredible properties such as strength, temperature resistance, and reduced weight compared to other materials.

    Arevo, the Silicon Valley-based 3D printing start-up, has developed a unique method to 3D print carbon fiber to boost scalability. To help the company achieve its goals, it has just received a cash boost of $12.5 million in a Series B funding round, led by Asahi Glass.

    Arevo hopes that the financing can help it achieve commercialization of its technology for aerospace, defense, transportation, automotive, consumer electronics, sports, medical and oil and gas industries.

    Additionally, it announced the appointment of Jim Miller as CEO. Miller joins Arevo from Amazon and Google where he held roles as vice president of supply chain and operations, respectively.

    Arevo’s Uses a Special Process for Fiber Coating

    So what makes Arevo’s composite additive manufacturing technology special? According to an interview by engineering.com with founder Hemant Bheda, Arevo’s process actually merges the carbon fiber strands with thermoplastics such as nylon or polyether ether ketone (PEEK).

    The technology achieves a highly precise coating of each fiber with the polymer. Importantly, it doesn’t destroy the fibers in the process. Arevo uses a laser DED technology to achieve this. Traditionally, engineers often use extrusion techniques in the process. However, the laser offers faster speeds and thus increased scale.

    Impressively, the porosity of the printed parts is less than 1%. At the same time, the material exhibits a strength that is 5x that of titanium at just a third of the comparable weight.

    Following the refinement of the material, Arevo plans to bring the technology to market. The company plans to focus on the software side of things next. Eventually, this should allow users to control and manipulate how the material is deposited.

    Print Carbon Fiber Bicycle in Just 18 Days

    To demonstrate the properties of its technology further, the company launched a carbon fiber bicycle in collaboration with Studio West. The resulting bike is a unique design. What’s more, the entire process required almost zero human labor, bringing the cost down to $300 for the bicycle frame.

    “We invited the designers to ride the bike and they were pleasantly surprised. They mentioned that, for big bike manufacturers who produce carbon bikes, it would take 15 or 16 iterations before they would get this quality of the ride,” Bheda explained. “What this means is that we can take the 18-month design cycle needed to create a new bike design and we can collapse it to less than 18 days.”

    Arevo is one of few companies currently working with carbon fiber to 3D print bikes. Japanese company Triple Bottom Line previously presented its fully 3D printed road racer.

    Similarly, the Australian company Bastion Cycles launched a 3D printed bicycle made of titanium and carbon fiber back in 2016.

  • CEAD Launches Industrial-Scale 3D Printer Tailored for Shipbuilding

    CEAD Launches Industrial-Scale 3D Printer Tailored for Shipbuilding

    Reading Time: 3 minutes

    The Netherlands-based additive manufacturing company CEAD is creating an industrial-scale 3D printer that is specifically engineered to help produce parts for ships and other maritime vessels. 

    Whether it be by land, air, or sea, 3D printing is becoming an integral tool across the transportation sector. Although we usually hear tales of how automotive or aerospace companies are using additive manufacturing technology, the maritime industry is also taking advantage of this emerging technology.

    In fact, the Dutch company CEAD is currently developing a large-scale 3D printer specifically designed for shipbuilding. The Continuous Fibre Additive Manufacturing (CFAM) machine will be able to print with engineering plastics and continuous carbon fiber composites.

    CEAD was founded by Maarten Logtenberg and Lucas Janssen, two former co-founders of the popular 3D printing company Leapfrog. The duo has apparently decided to shift their focus from desktop FDM printing to the industrial market.

    CEAD Develops Industrial-Sized Printer Designed for Yacht and Ship Building

    The first CFAM 3D printer will offer a generous build volume of 4 x 2 x 1.5 meters. According to CEAD, the printer is equipped with a high-temperature granule extruder that is capable of printing around 25 kg of material per hour.

    “The CFAM printer is a large-scale thermoplastic composite 3D printer for industrial use. The machine we are developing is capable of printing 24 hours a day with engineering plastic and a continuous fiber on a very large scale. The technology is based on a single screw extruder with a weight of around 150kg, capable of temperatures of up to 400 degrees Celsius,” Maarten Logtenberg, executive director of CEAD, recently told Digital Trends.

    Users will be able to splice carbon fiber composites with a range of engineering-grade plastics, including PP, PET, ABS, PLA, and PEEK. CEAD says that the first CFAM prototype will be ready by the middle of 2018.


    The Netherlands-based 3D printing company is stationed in Rotterdam, which just so happens to be a major port city and hub for shipbuilding.

    CEAD already has a few customers onboard, including Poly Products B.V., a company that produces composite products for the maritime industry. The marine engineering firm Royal Roos also plans to use the printer to create new parts that will reduce the weight of maritime vessels.

    The two companies have already placed orders for the CFAM 3D printer, which CEAD hopes to build in 2019. While the machine is still under development, the news of a large-scale 3D printer tailor-made for shipbuilding should definitely create waves of excitement throughout the maritime industry.
