Extruder is the most crucial part of a 3D printer; designers have developed many ways of improving on the original extruder. GT4 is the fourth generation extruder of Geeetech; the cold end of which is composed of plastic parts that are 3D printed, such as the pinion and gear, easy to be assembled. The hot end of which adopts high-quality aluminum alloy heat radiator and brass nozzle, with stainless steel pipe as feeding pipe, this ensures good heat insulation effect and can help prevents blockage of the filament. Besides, the 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.

Attention please: the wheelbase of the support shaft of GT 4 is 45mm, which is fit to Prusa Mendel I3, make sure it fits your machine before placing an order.

    ola, boa tarde qual é o passo para esta extrosora, eu tenho 815? eu tenho uma geeetech i3 x e estou com dificuldades em configorar, porque sempre que começa a imprimir o esteps/mm muda automaticamente para 161, será que no arduino esta a limitar?? obrigado
