Researchers at MIT have unveiled the world’s first chip-based 3D printer, small enough to fit on a coin, that prints without any mechanical components. Leveraging advanced silicon photonics, this miniature device uses nanometer-scale optical antennas to emit light directly into a resin well, curing designs at speeds measured in seconds .
Currently capable of producing flat, 2D micro-patterns, the team is working to evolve the system into volumetric 3D printing, using visible light holograms to build intricate 3D forms. While the macro-scale functionality remains in development, this proof-of-concept could eventually empower wearables, sensor arrays, and lightweight micro-structures, revolutionizing embedded manufacturing and chip-scale additive workflows .
