The SLA/DLP printing material and the support material are derived from the same photosensitive resin, so the printed part is easily damaged when the support is removed. PolyJet can use multi-nozzle, while printing photosensitive resin, water-soluble or hot-melt support materials can be used. Repeat the foregoing process until the workpiece is printed.Ĭompared with SLA printing technology, the laser spot used is 0.06-0.10 mm, and the printing accuracy is much higher than SLA. The nozzle moves along the X/Y axis,The photosensitive resin is sprayed on the workbench, and the UV lamp emits ultraviolet light along the nozzle movement direction to cure the photosensitive resin on the workbench and complete a layer of printing Īfter that, the workbench drops one layer thickness along the Z axis, and the device Repeat the above process to complete the printing of the next layer Its molding principle is the same as SLA and DLP, which is cured by photosensitive resin under ultraviolet light. The picture above shows the structure of PolyJet polymer jet system. The print head sprays droplets of photosensitive resin on the bottom of the print, and then cures it layer by layer with ultraviolet light. PolyJet printing technology is similar to traditional inkjet printers. Polymer Jet (PolyJet, PJ) technology is a patented technology launched by Israel Objet (incorporated into Stratasys in 2012) in early 2000.
Since this machine is often used to make human anatomical replicas, engineers hope it can also be good at producing wearable devices for body parts.
According to Allen, using 3D printing to iterate jacquard effectively "gave the team time to explore and optimize solutions for the design."Īfter successfully using the beta version of Stratasys' KeyShot 3D modeling software in the development of Jacquard, the ATAP team now intends to use other solutions in future iterations, such as the digital anatomy system. The use of J8 also enables the team to quickly produce prototypes that reflect the quality of the final product, while reducing delivery time from three weeks to only one day. For example, using the printer's Pantone matching system, engineers can create sensors that can effectively reflect the texture of wood or leather of the host material. We are always looking for and exploring new technologies, but the most important thing is application-driven innovation."ĭuring the lead Jacquard design process, the ATAP team found that Stratasys' J8 machine provided great flexibility.
Allen explained: "Our team is really looking for solutions. The sensor itself is also small and flexible, which means that Google can integrate it into almost any fabric, but the merging process can be complicated and often requires multiple technologies to assemble.įor Allen,This is the reason why Google chose Stratasys technology to simplify the process and obtain the benefits of specific applications. When wearing a device that supports Jacquard, users can simply swipe or click to pause music, take photos, and even answer calls. These wearable devices all contain a tiny embedded tag that provides users with interactive control of various digital devices without the need to hold them. Current products include Levi jackets with integrated sensors and Adidas insoles. In the past five years, Google The commercialization of the Jacquard platform has been steadily realized. △ Google’s ATAP team used Stratasys’ 3D printing technology to prototype the Jacquard device several times (pictured). The future is coming much faster than we thought." By adopting the J8 system of Stratasys, the ATAP team is now able to quickly complete the prototype design of the device and deploy it in interactive "gaming sneakers" and "smart backpacks".ĪTAP technical project manager and laboratory leader Bryan Allen said: "Printers have really caught up with the way designers think about design and materials. This 3D printed label can be affixed to everyday clothing items, endowed with motion sensing functions, and allows the wearer to control the phone through certain gestures. On January 29, 2021, Antarctic Bear learned that Google's Advanced Technology and Projects Department (ATAP) used Stratasys' PolyJet rapid prototyping technology to prototype the "Jacquard" wearable electronic sensor.
Google also used this technology when developing wearable electronic devices to give full play to the creative talents of designers. Antarctic Bear Guide: The role of 3D printing in product prototyping is unquestionable.
