This all-metal M2 hotend contains a ceramic heater and thermistor. It has an improved nozzle structure, where the heating block and nozzle are connected with a screw thread. This means there is less chance of material leaking during printing. The nozzle is made of SKD11 hardened steel, which means this hotend can handle a temperature of up to 320 ˚C. Because the radiator and the heating block are connected by two screws, there is less chance of problems during 3D printing at high speed. Finally, there is better heat conduction thanks to the use of a nickel-plated chromium zirconium and copper alloy. This hotend is suitable for the P1 series 3D printers from Bambu Lab.
