Makerbot has no US support whatsoever. They have no phone number. Their online chat is never manned. Our company wants to establish Makerbot as a supplier and would simply need a W-9 and email to send PO's. I have asked twice on their website and no response. Yet they fill my email box with promos and other garbage. I've learned how to rebuild the Method X extruders (thankfully) because I can't get or find parts on their website. Never again. We need more printers here but I will NOT be buying the Makerbot carbon. Pass
