Features: Brand new and high quality All-metal design, and the nozzle is made from copper alloy and hardened steel. Support 300C high temperature printing, suitable for more consumables, such as ABS, PETG, PP, PC, nylon, etc. The heat insulation parts are made from titanium alloy and copper, with extremely thin wall thickness and excellent heat insulation performances. The roughness of the nozzle inner wall is less than or equal to Ra0.4, and the feeding is smoother. Titanium alloy supporting high-temperature printing (300C) can reduce the heat conduction of heating block, and copper has excellent thermal conductivity, which can accelerate heat dissipation and prompt the overall performances.
