1、Mighty Compatibility: This upgraded hotend kit is compatible with Bambu Lab X1-carbom Combo P1P 3D Printer, supporting filament types such as PLA, ABS, PETG, TPU, PP, PC, Nylon, PEEK, PEI, etc. 2、Heater Block: Chromium zirconium copper nickel plating, small size and lightweight, withstand high temperature up to 300℃, with faster thermal conductivity. 3、Hardened Steel Nozzle: Made of quality material make it more wear-resistant and extend its service life; RA0.4 inner wall roughness of the throat and nozzle is, which reduces the phenomenon of blockage and improves the printing quality. 4、Design Upgrade: Nozzle structure upgrade, threaded connection, heating block and pipe, solve the phenomenon of falling off, and can be disassembled and replaced, reduce the cost of use. And the throat structure is upgraded as well, and the step limit is added to cooperate with the heating block, which perfectly solves the problems of leakage and falling off. 5、What You Get: 2 x 0.4mm hardened steel nozzle, 1 x Integrated pipe heating block, 1 x Heat sink block, 1 x Thermal Grease, 2 x Wrench. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
