UC Berkeley and Prusa Open Up the World of Volumetric 3D Printing

The University of California, Berkeley (UC Berkeley) has released OpenCAL, a DIY volumetric 3D printer developed in collaboration with Prusa Research and Formlabs. Formlabs produces the resin, which will be sold through Prusa Research. Several printers are already up and running, including units installed at MIT, the National Institute of Standards and Technology (NIST), and Purdue University.

The UC Berkeley team extended the Computed Axial Lithography (CAL) process to an open-source machine. Professor Hayden Taylor developed CAL together with scientists from the Lawrence Livermore National Laboratory, and the resulting system was tested in space. In OpenCAL, the resin vial rotates while a projector illuminates it. This can lead to a much faster, layer-free path to manufacturing. Usually
