Patent pending Rotech Barrel for the Typhoon 3D printer. Available for 1.75 and 3 mm filament.
Rotech’s patent pending hot ends thread the nozzle directly onto the barrel and the whole assembly threads directly into the heat sink, while the heater block just slides over the nozzle. This allows you to slide the heater block off and easily change nozzles and barrels without removing the heat sink from the extruder. The process is quick and easy, and gives you more options for filament sizes and how quickly your filament gets extruded.
