Abstract
A system for additive manufacturing includes a multi-material vat that includes a plurality of resins. The system also includes a robotic arm that provides at least six degrees of freedom of motion, where the robotic arm moves with the six degrees of freedom to draw resin out of the multi-material vat to form an object. The system further comprises a processor operatively coupled to the robotic arm and configured to control movement of the robotic arm in the six degrees of freedom.
