CAT scan-inspired printer produces whole objects in seconds

Researchers have 3D printed intricate objects by combining a standard projector and a rotating vial filled with a liquid that hardens when exposed to light. The printer can produce detailed structures in seconds, such as a tiny model of Auguste Rodin’s sculpture The Thinker.
