The Kossel Clear uses 1.75 mm filament in a 0.4 or 0.5 mm nozzle, printing at a layer height of 100 microns. It can be ordered as a PLA printer with a round, acrylic build platform, or with a square, heated glass bed for ABS. The PLA version's build envelope is 279 mm diameter x 279 mm Z-axis. The ABS version has a build envelope of 200 x 200 x 279 mm. Various upgrades are available, including an LCD/card reader, aluminum arms (replaces acrylic arms) and OpenBeam extrusions for the frame.
Pledges range from $500 for a PLA kit to $1,100 for a fully assembled and tested ABS unit. Turnaround dates are relatively short for a crowd funded printer.
