Features: Brass material has good thermal conductivity, high hardness, and high roughness of the inner wall of the pipeline, reducing blockage High temperature resistance, fast thermal conductivity, more stable printing, tightly fitting joints to prevent material leakage and breakage. The contact surfaceis flat, solve theproblem of consumables leakage and effectively preventing printing head leakage Cutting chamfer design reduces the resistance of edges and corners to consumables, avoiding unsmooth wire discharge and blockage The inner wall is smooth without burrs, with a small viscosity coefficient and smooth wire discharge, effectively preventing printing head leakage.
