New 3D Printing Process Solidifies Objects with Rays of Light

Researchers at the University of California, Berkeley, developed a new 3D printer that uses a special light-sensitive resin that solidifies into objects in a matter of minutes. The researchers nicknamed their machine the “Replicator” after the Star Trek device that materialises any object on demand.

This new 3D printing process creates whole structures by projecting light into a resin that solidifies almost instantly. On the other hand, the usual 3D printing method creates pieces by depositing various kinds of material layer by layer.

New Manufacturing Opportunities

This new process allows different manufacturing opportunities such as adding a handle to a metal screwdriver shaft by plunging the screwdriver in the resin. Another traditional 3D printer would struggle to do this for example. Furthermore, it can also create objects which are smoother, more flexible and more complex. The technology could have great potential in medical fields, especially where transparent parts are needed, researchers said.
