New 3-D printer transforms liquids to solid objects in minutes

3-D printing with light. A new 3-D printing technique shines light rays onto this yellow liquid, creating solid, 3-D objects. The syrupy liquid is light sensitive and hardens when exposed to a certain amount of light. 
Nicknamed the “Replicator,” the printer custom-makes objects; like a model of a jaw, a mini-screwdriver, or even “The Thinker”.

Researchers generate a 3-D model of an object and a computer program converts the 3-D model into a movie. The liquid rotates and reacts to the movie’s patterns of light. The “Replicator’s” objects are more smooth, flexible, and complex than traditional 3-D printed objects.
