The heating block is upgraded from brass to nickel-plated chrome-zirconium copper, which is small in size and light in weight, can withstand high temperatures up to 500C, and conducts heat faster;The radiator and heat shield can be disassembled and locked through the side fixed shaft, reducing the cost of use.The interference between the TC4 titanium alloy thermal break tube and the heat block increases surface at the bottom of the throat, completely eliminates the phenomenon of shedding, and reduces the possibility of water leakage.The nozzle is made of quenched steel, and it is quenched and hardened to more wear-resistant and prolong its service life; the roughness of the throat and the inner wall of the nozzle is RA0.4, which reduces the clogging phenomenon and improves the printing quality; the nozzle structure is upgraded , The heating block and the throat are connected by threads, which solves the problem of shedding, and can be disassembled and replaced to reduce the cost of use.The product is compatible with X1-carbom Combo P1P 3D printer, and supports ABS TPU PP PC Nylon, , PEI and other consumable types.Type:BColour:As ShownMaterial:Copper Nickel PlatedPackage Contents:1 set x hardened steel nozzle full metal hotend kit1 x silicone sleeve cover1 x extra hardened steel nozzleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
