A joint team of researchers from Japan and Singapore have developed a new technique for creating high resolution (40µm) hybrid plastic/metal parts. It’s called multi-material digital light processing 3D printing (MM-DLP3DP).
Similar to standard resin 3D printing, this process adds a few extra steps. Firstly the printer uses both resin and a pre-cursor material. Once printed, the parts are further processed in a plating bath, and the pre-cursor material is plated, while the standard resin is not. This allows for intricate and nested plated metals and could potentially be used as a way to create 3D circuits.
