Phaetus Dragon Standard Flow Hot-End Incl. 1x Copper Plated Reprap M6 0.4 mm nozzle. All-metal kit, with overall high temperature resistance up to 500 ℃. Heat break with an ultra-thin wall thickness as thin as 0.1 mm, realizing an excellent thermal insulation. Increased rigid support structure guarantee the heat break remaining intact under the impact of external force. Integral frame rigid structure makes nozzle replacement more convenient without grasping the heat block. The inner hole roughness of nozzle and heat break 0.4, which allow a more smooth movement of filament, resulting a higher resolution prints. ST and HF version are with the same overall dimension, which realizes a zero barrier for interchangeability. The hot-end is mainly composed of copper alloy material which has the advantage of faster heating and better heat dissipation. Flexible combined structure design makes a strong compatibility.
