Silicon-photonics-enabled chip-based 3D printer
Summary
The paper introduces a chip-based 3D printer built from a single millimeter-scale silicon-photonics chip that emits visible-light holograms into a resin to cure prints without moving parts. It demonstrates voxel, line, and 2D pattern printing using a visible-light integrated optical phased array and a visible-light-curable resin, signaling a path to compact, low-cost volumetric printing.
