The patent describes a 3D printing method to produce active electronics made of semiconducting materials — a method that only uses a 3D printer. “These disclosed semiconductors may provide a multitude of end uses, such as wearable displays and/or continuous on-eye glucose sensors,” the patent said. “These devices may also include a range of functionality, from including quantum dot light-emitting diodes (QD-LEDs), MEMS devices, transistors, solar cells, piezoelectrics, batteries, fuel cells and photodiodes.”

nice find Hawk! National Geographic has an article about this same tech building organs. It is the issue with the female Astronaut cover.
