Today we can across a Catastrophic failure of one of the FlashForge 3D Printers. The seniors (12th grade) students took it apart to find what the issues was. Unfortunately the head to the printer is beyond repair, another has been ordered and should be here in about one to two month. It was a great teaching point, we when over how plastic injectors worked and PID temperature controllers. We are going to make mechanical drawing in Solidworks and machine our own nozzles so we can have spares on hand.
