Abstract

This paper proposes a novel chip-based 3D printer using silicon photonics and photochemistry. The system uses a millimeter-scale photonic chip with no moving parts to emit reconfigurable visible-light holograms, curing liquid resin to create 3D objects. A proof-of-concept demonstrates stereolithography-inspired 3D printing using a visible-light beam-steering integrated optical phased array and visible-light-curable resin, successfully printing sub-millimeter voxels and patterns in one and two dimensions.
