Lulzbot is the poster child of the RepRap project. Everything they do is big-O Open. At CES, Lulzbot launched the MOARstruder, a tool head with a 1.2mm nozzle diameter. That pushes a lot of plastic out, allowing for faster print times. This is the same nozzle diameter as the largest E3D Volcano, and from the big prints sitting around the booth, the results are similar: you get faster prints at larger layer heights, and the layer lines become a design feature.
Also announced by Lulzbot this week is the release of Cura 2 (Lulzbot edition), a partnership with the Blender Institute to develop a streamlined version of the best Free 3D modeling software available, and a collaboration with Monkeyprint to develop Free Software for resin-based 3D printing.
