  • Repeatability: better than 0.03 mm (30 micron)
  • Build volume: cylindrical, 255mm diameter, 240mm height.
  • Footprint: triangle, 450 mm width (360mm OpenBeam + printed corners).
  • Frame height: 600 mm.
  • Print surface: heated round glass, doesn't move.
  • Mass of end effector with hotend: less than 50 grams.
