Feature:
1) Throat Adapter: Bimetal Heat break, Copper and Titanium TC4. Titanium TC4 reduces heat upward conduction at the heating position, and copper for heat dissipation to accelerate heat conduction. It has High temperature resistant up to 500C degree, with different thermal conductivity and smooth inner wall reduce 3d printer material clogging. A wide compatibility with different filaments, such as PLA, TPU, PETG, Wood, ABS, etc.
2) Heating Block: Aluminum, not copper. High Temperature, high precision, stable performance.
3) Heater 40 W - 24V
4) Thermistor NTC 100k - cable also fit XL.
