A new method for 3D printing

 

Where as the usual 3D printing methods create a 3D object by printing it layer by layer a recent publication in Science DOI described a method by which the objects were created by passing light through liquid acrylate. Computed Axial Lithography (CAL), allows generation arbitrary geometries volumetrically through photopolymerization. The process was inspired by the 3D image construction used in CT scans.

The exposure process takes about two minutes for an object a few centimetres across; the team recreated a version of Auguste Rodin’s sculpture The Thinker a few centimetres tall.

The supplementary materials include details for printing several objects

I've added it to the 3D printing page.
