Abstract
A Blu-ray optical pick-up unit (BOPU) is hacked and repurposed into core optics of a palm-size 3D printer for micro/nanoscale features printing. The BOPU focuses 405 nm laser to a 319 nm spot (Gaussian waist diameter) that can polymerize a photopolymer on a substrate. A closed-loop three-axis nanopositioner actuates the substrate for three-dimensional printing. Multiple microscale line features are printed to evaluate the printing resolution. A preliminary experiment shows that the highest achievable horizontal printing resolution is 1.47 µm, which is smaller than that of conventional single-photon 3D printers.
