MIT and UT Austin researchers have developed what they claim is the world’s first chip-based 3D printer, small enough to fit on a U.S. quarter. Using a single silicon photonic chip with a nanoscale optical antenna array, the system emits visible-light holograms into a resin vat—curing flat patterns in seconds, without any moving parts .
While currently limited to two‑dimensional shapes (like an MIT logo), the team is working toward volumetric 3D printing, where entire 3D forms are cured instantaneously by a holographic light projection .
Applications could include portable medical device fabrication, on-site repairs, wearable sensor printing, and embedded microstructure production, fundamentally redefining additive manufacturing .
