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 the cooling fan directly faces to operation area providing better heat insulation. As a long-range extruding machine this product is separated from the extruding head which greatly reduces the weight of extruding head ensuring more sensitive finer and more stable printing.
