New device paves the way to 3D-printed organs, food

From prosthetics and implants to dental crowns and hearing aids, 3D printers are being used to manufacture a whole host of customized medical devices for patients in need. So, why not organs, too? Not surprisingly, the intricate, mushy tissues that make up most human organs are not as easy to 3D-print as stiff scaffolds for prosthetic devices or chassis for hearing aids. But a new device created by engineers at UC Berkeley promises to make the 3D printing of biomaterials like organs and food a lot more viable. Living cells require very specific temperature and chemical conditions to survive and will often deteriorate during a lengthy printing session. The new device uses identical printers to create multiple layers simultaneously, and then stacks them one on top of the other to form the 3D structure. This arrangement speeds up the printing process and makes it more likely that the cells […]
