Assembled GT8 Extruder 0.3-0.5mm Nozzle All Metal J-Head Hotend For 3D Printer


Geeetech GT8 extruder adopts high-quality aluminum alloy heat radiator and brass nozzle, with stainless steel pipe as feeding pipe, which ensures good heat insulation effect and prevents blockage. Besides, its surface is covered with anodic oxide coating, which can resist oxidation corrosion and increase nozzle hardness, thus ensuring better heat insulation, stronger corrosion resistance as well as finer and more stable printing.
