We have investigated resin formulations that enable multimaterial part production via digital light processing additive manufacturing (DLP-AM). The system includes a liquid resin vat containing orthogonal initiators and monomer classes, each uniquely activated by specific wavelengths of light. The approach enables production of multimaterial and gradient parts as a function of the color images used during the printing process. We will present on the resin development, equipment development, materials characterization, current limitations, and envisioned applications.
