We bought this Makerbot Replicator 2 3D printer for our prototype and development shop about 5 years ago. It works flawlessly with extruder temperatures reaching 250ºC easily. It is a great printer for accurate PLA, with both fans working. A new idler pulley was put on about a month ago. We've always used the Makerbot Desktop slicer with USB to computer without any issues. There are even the original rubber feet on the bottom for vibration and the filament holder in the back. The only reason we are trying to resell it is due to the fact that we just got two new FormLabs SLA machines and it is taking up valuable shop space.
