All-metal integrated design - The nozzle and heat break adopts an all-metal integrated design,facilitating quick disassembly and convenient replacement. Wide Application - The heat break is made of titanium alloy, which reduces heat conduction The nozzle is composed of copper alloy and hardened steel, supporting the printing of filaments such as PLA, ABS, PETG, TPU, PP, PC, PLA-,PA-, PET-, etc. Precision Craftsmanship - The inner wall is smooth and has no obstruction. The inner hole roughness is Ra Less than 0.4, and the feeding is smooth. The precision machining is impeccable, the hole has no burrs, and the printing is stable and not easy to block. And tightly fit joints effectively prevent filament leakage during printing This nozzle kit is perfectly design for K2 Plus 3D printer.
