A CoreXY 3D printer being developed by Mark Rehorst at MMS. Already mostly finished, it has a 300 x 300 x 698 mm print envelope, is fully enclosed and will soon be heated for printing ABS reliably.
UMMD is fully functional (except the enclosure heater) and was displayed and operational at the Milwaukee Maker Faire last week.
