Features: Brand new and high quality High thermal conductivity, high-speed flow printing, uniform heating, volume twice that of ordinary nozzles. Support 600mm/s printing speed; The roughness of the inner wall of the pipeline is less than 0.4, which reduces the blocking phenomenon. High temperatures resistance, heat conduction and more stable printing; brass plating on the surfaces has good conductivity, corrosion resistance and rust resistance, which greatly reduces the adhesion between consumables and nozzles and makes extrusion smoother. Suitable for most materials, such as ABS, PETG, PC, PEKK and PPSU. Suitable for high temperatures 3D printing that other Nozzle cannot handle and printing.
