The 3D printing of glass has been in the news quite a lot lately, with several breakthroughs coming in the last couple of months. Micron3DP is releasing its glass 3D printer after installing several units at its own factory, and researchers from the Karlsruhe Institute of Technology (KIT) recently developed a method of 3D printing glass on an SLA printer. Now scientists at Lawrence Livermore National Laboratory (LLNL) have come up with a new way of 3D printing transparent glass for applications involving optics.
