Printing Micron-Scale Benchies With Resin and Turmeric

Resin 3D printing has opened up a whole new scale of resolution for hackers, but the technology can go still finer; commercial micro-SLA and two-photon polymerization printers can print items with sub-micron feature sizes, but the machines are well out of reach for hackers. There’s more than one way to get such high resolution, though, as [Diffraction Limited] demonstrated with his micron-scale resin printer . The printer builds on [Diffraction Limited]’s previous micro-manipulator and fiber-cou
