Modefine 3D M1 hotend for X1series (ceramic heater+thermistor)

This all-metal M1 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 high-speed 3D printing. 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 X1 series 3D printers from Bambu Lab.
