A proof-of-concept 3-D printer can fit in the palm of your hand.
Science News reports: "Rather than relying on a symphony of moving parts — like a bulky tabletop 3-D printer — the device uses antennas on a tiny chip to guide a light beam into a well of specialized resin above the chip. When exposed to the visible light, the resin cures into hard, customizable shapes in just seconds."
@ScienceDesk sweet, soon we can print microplastics directly into the bloodstream.
@ScienceDesk So an SLA printer but tiny. The comparison to FDM printing doesn't make a lot of sense.
