Hackaday user TTN and Matt Kimbal have been working on development of the IcePick Delta. The IcePick Delta is a 3D printer designed without linear rods or bearings. The final outcome of the 3D printer, nearing completion, will be a streamlined machine that is simple and affordable, with easy maintenance due to the design which features less parts than usual.
