Tricolor 3D printer Reprappro Mendel Roadblocks model

Characteristics of fantastic three colors printing 3D print:
support three different material to print, for example PLV, ABS, PVA(realize special support material to print, PVA)
three different colors material
change different diameter nozzle, to realize different thickness of layor printing, big nozzle satisfy inner filling, small one
satisfy out printing5 mm thickness aluminum alloy surface temperature, durable heat up faster
during print lower sound
- support component printing, to reduce the edge warping phenomenon
Printing size:180230140mm,external dimension:470450400mm
