OpenCAL

UC Berkeley has released OpenCAL, an open-source volumetric 3D printer developed in collaboration with Formlabs and Prusa. Volumetric printing builds objects by solidifying resin in three dimensions rather than layer by layer, and open-sourcing the design could let researchers and hobbyists experiment with the approach at low cost. The project is being reported in the additive manufacturing press as a notable step for accessible volumetric 3D printing.
