MIT Demonstrates Fully 3D Printed, Active Electronic Components
https://hackaday.com/2025/02/19/mit-demonstrates-fully-3d-printed-active-electronic-components/

One can 3D print with conductive filament, and therefore plausibly create passive components like resistors. But what about active components, which typically require semiconductors? Researchers at MIT demonstrate working concepts …read more (https://hackaday.com/2025/02/19/mit-demonstrates-fully-3d-printed-active-electronic-components/)
