FDA, NIH and VA already possess the resources necessary to quickly test and share 3D-printed designs of face masks, shields and other supplies that medical personnel now need, so they likely came ...

Verify your 3D graphics hardware is working with a mesmerizing demo of spinning gears.

It's powered by a DC motor running a crankshaft that feeds a set of fluid-filled bellows pumps, which move the legs. Another version uses a 3D-printed gear pump for continuous flow.

UA's new 3D-printing lab at the Lighthouse will have six rooms, each with a technician. This is where more Architechs (and other 3D-printed gear) will be made. Lighthouse Director Adam Bayer.
