Computed Axial Lithography (CAL) is a fast 3D printing technique that can create objects from photopolymer resin in a matter of minutes without the need for traditional layering.
The resin sits inside a rotating transparent cylinder, whilst UV light is projected inside in a pattern, generating a 3D object in the resin through a single exposure, rather than through layering.
The technique can create high-resolution prints, and also allows objects to be embedded into the resin during the print.
Berkeley team Open CAL has announced it will open source its CAL machine, and is seeking to collaborate with the maker community on its Discord channel.
This could pave the way for enterprising makers being able to create tabletop-sized machines, and CAL becoming more accessible.
