RepRapMicron Uses Fibre Optics To Print Tiny Benchy in Resin

The 0.5 mm Benchy made with the MicroRepRap UV head. The RepRapMicron (also µRepRap) is pretty much the microscopic take on what RepRap did for more macroscale manufacturing, with the most recent innovation being a UV print head, called the PIKA UV Head . What this does is use off-the-shelf optical fiber and UV LED modules to create 3D structures in-situ in a UV resin, allowing for pretty small structures to be printed, down to a resolution of about 9 µm.
