AREVO 3D printing the carbon fiber Emery One eBike frame

Arevo, the Silicon Valley based firm will be 3D printing the carbon fiber eBike frame and the eBike will be sold under the Emery Bikes brand as the Emery ONE and that they've partnered with Franco Bicycles, a specialty bike manufacturer in California, to bring the Emery ONE to the public.

The frame is 3D printed as a single, solid body using Direct Energy Deposition (DED) and a multi-axis robotic motion system. Since it's carbon fiber, it's five times stronger and three times lighter than titanium, making it an ideal material for a bike frame where strength and weight are important. Using 3D printing also enabled faster iterative designs for the frame, cutting the development time from 18 months to just a few days.

“We chose AREVO technology because its iterative and flexible design represents the new age in composites manufacturing, and we wanted to be the first bike company to help lead this revolution,” said Hector Rodriguez, Co-Founder of Emery Bikes. “AREVO's continuous carbon fiber technology has been instrumental in achieving the ride quality and high-performance requirements we set out to accomplish with the Emery ONE.”

AREVO is manufacturing the frames in Milpitas, California, but interested parties could see the prototype Emery ONE at the Sea Otter Classic cycling event in Monterey, Booth S9 until April 14th. “This is the first Composite additively manufactured bike frame and it represents an important milestone for the AM industry as AREVO is delivering on the promise of on-demand manufacturing of composite parts in volume now,” said Hemant Bheda, AREVO Co-Founder and Chairman. AREVO's technology was designed for industrial fabrication, and they do produce jigs and fixtures for other clients, but those parts are visible only to industry insiders. By 3D printing a bike frame for the masses, AREVO is bringing more attention to the manufacturing capabilities of 3D printing.

Additionally, 3D scanning and data capture devices are being developed and rolled out to generate the necessary biometric and topographic information.

From rapid prototyping to advanced manufacturing

Prototyping with 3D printing is already the norm in the footwear industry, though its use is expected to continue to grow. Faster growth is anticipated in 3D printed end-use parts, including insoles, midsoles, and uppers. Personalization isn't the only driver for this shift as increased performance and comfort are also achieved through 3D printing. The internal geometry of an insole can have a big impact on its spring and cushion, so engineers are pushing their manufacturers to integrate 3D printing technologies. Final parts already represent 34% of all 3D printed footwear revenues so adoption is clearly accelerating. Midsoles are forecasted to represent the majority of future revenues, followed by insoles. Stereolithography (SLA/DLP) vat photopolymerization systems are currently the preferred technology for 3D printing footwear, but powder bed fusion and voxeljet technologies will likely take some of the market share as they're more ideal for mass production.

ESJET printing technology for large area active devices awarded

ESJET printing is a new printing technology for large-scale, solution-processed displays of the future. It enables higher hresolution and drop on demand printing. The Potsdam Fraunhofer Institute for Applied Polymer Research IAP, together with its project partners imec and TNO/Holst Centre, has developed this printing technology for solution-processed displays of the future. The Fraunhofer Institute for Applied Polymer Research IAP, imec and TNO/Holst Centre have been awarded with the Best Institute / Academic R&D Award at IDTechEx Printed Electronics 2019.

ESJET printed active matrix 0,5‘‘ display with 10 µm pixels and a 300ppi resolution.

The award is granted for “significant contribution over the past 24 months to the understanding of the principles and accrued knowledge behind printed electronics”, the guidelines state. Dr. Richard Collins, Senior Analyst at IDTechEx, presented the award on April 10th, 2019. Within the EU project, Hi-Response, 13 consortium members are working together to develop a highly innovative Pulsed Electro-Static Printing Technology for high resolution printing for different applications. Within Hi-Response, the researchers of the Fraunhofer IAP, imec and TNO/Holst Centre have developed high-resolution ESJET (electrostatic jetting) printing for conductive and emissive polymers, which opens up new possibilities for various applications. The technology has the potential to be implemented for high-resolution printing of AM OLEDs with pixel sizes below 10 µm yielding in RGB resolutions beyond 500 ppi. This technology - being scalable - enables large area printing of active devices. Furthermore, the ESJET can deposit a much wider range of viscosities from 1 to 10,000 cP, compared to 1-40 cP for inkjet printers.

The advantages of the technology of ESJET printing

“With ESJET, we are able to significantly reduce pixel sizes for printed AM OLEDs”, Dr. Christine Boeffel, project manager at the Fraunhofer IAP says. “One of the remarkable things about the technology is that even at pitches of 25 µm, pixel sizes down to 10 µm are printable. For our demonstrator we printed 62967 single 10 µm wide dots to make a working display with a 300 ppi resolution.” Imec and TNO/Holst Centre developed AM OLED backplanes and provided them to the Fraunhofer IAP for processing of the OLED front plane. High-resolution ESJET printing was implemented for the deposition of the PEDOT:PSS hole injection layer consisting of the print of 62967 single 10 µm wide dots on the 0.5 inch wide active matrix backplane. The subsequent layer of the emitting material was processed by spin coating followed by thermal evaporation of the transparent electrode. “It is a great milestone to print OLED materials in such small dimensions. Improving in the printing resolution opens new possibilities for solution processed OLED display”, Dr. Tung-Huei Ke, senior researcher at imec says. “We have reached an important goal getting the technology of ESJET printing this far. We are convinced that pixel sizes can be reduced even further below the mark of 10 µm. We plan to print OLED materials for RGB display applications at 300 ppi in future projects”, Dr. Manuel Gensler, researcher for ESJET printing at the Fraunhofer IAP says. “With the display industry searching for new and innovative ways to increase display resolution as well as to include new user interfaces into the full display area, high-resolution printing technology is a key enabler to realize these goals by printing OLED materials as well as other functional materials at high resolution”, Dr. Auke Jisk Kronemeijer, GEN1 TFT Pilot Line Manager at TNO/Holst Centre says.
