News Summary

• 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.
• 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 his previous micro-manipulator and fiber-coupled laser.
