Development of a Novel Multimetal 3D Printer via Mask Image Projection Based Vat Photopolymerization

Mask image-based vat photopolymerization 3D printing, which selectively cures photoreactive resin, is an ideal technology for fabricating multimaterial objects by integrating a material exchange process during printing. Currently, two common metal additive manufacturing technologies, powder bed fusion (PBF) and material extrusion, are limited to a small range of printable materials and require specialized equipment that can be costly to the end user. The objective of this project is to construct a low-cost vat photopolymerization printer that is capable of interchanging photocurable metal precursor materials to obtain a multimetal structure using a layer-based approach.
