Eliminating Plastic Waste by Transitioning Machine Shop to Produce Its Own 3D Printer Filament
… students use injection-molding and thermoforming machines, and 3D printers for prototyping. All of these tools generate waste products; LMP throws out barrels of plastic every semester. To better align with MIT’s commitment to fighting climate change, LMP needs to cut down on its excess plastic. …
