Metal 3D printing nozzle assembly

Abstract

The invention relates to the technical field of 3D printing, in particular to a metal 3D printing spray head assembly, and solves the problems that a used metal 3D printing spray head assembly is likely to be blocked due to residual metal powder, and gaps are likely to be generated among metal powder in a metal powder conveying hose in the 3D printing process of the metal 3D printing spray head assembly. Comprising a metal 3D printing nozzle assembly. According to the high-stability feeding and wire discharging mechanism, downward pressure can be continuously provided for metal powder, and residual raw materials attached to the interior of equipment can be automatically scraped off through the full-automatic cleaning and anti-blocking mechanism; therefore, the metal powder can be extruded more compactly, the density of the powder is improved, the metal 3D printing spray head assembly can continuously extrude wires, and the residual raw materials are automatically cleaned, so that the printing spray head can be blocked due to the solidified raw materials.
