“A 3D printer that creates an entire object at once.”

The Replicator

Nature shows off the replicator, a 3D printer capable of creating an object all at once using light.

As the projector cycled through the images, which covered all 360 degrees, the container rotated by a corresponding angle. “As the volume rotates, the amount of light received by any point can be independently controlled,” says Taylor. “Where the total amount exceeds a certain value, the liquid will become solid.”

This is because a chemical in the resin absorbs photons and, once it reaches a certain threshold, the acrylate undergoes polymerization — the resin molecules link together into chains to make a solid plastic.
