The OpenCAL project

After we introduced the computed axial lithography process, several research groups expressed interest in building a CAL printer for experimental work with materials and new applications. We realized that it would be helpful to the research community to make available our hardware designs and our software for generating projection images from a target digital geometry model such as an STL file. We now maintain a Github organization here, which has repositories for both hardware (Solidworks files plus a component list) and software (the Python VAMToolbox, with legacy Matlab code also retained). It is free for non-profit, research and educational uses via a GPL3 license (but not for any commercial uses of CAL, which must still be licensed case-by-case: contact us for more information). We warmly welcome contributions (pull requests) to the repositories from research groups who make advancements and wish to share them with the world.
