Abstract

The invention discloses a multifunctional 3D printing head, which is suitable for 3D printers in any hot melting additive stacking forms. The 3D printing head includes a hot melting chamber, an extrusion pump, a double sleeve spray nozzle, a hot air polishing and cold air shaping apparatus. During 3D printing by means of the multifunctional 3D printing head, a plurality of sub spray nozzles in different pore diameters can be selected conveniently. A raw material is hot-melted in the hot melting chamber, and then the hot-melted material is outputted by means of an extruding pump in an extruded manner. The double sleeve spray nozzle extrudes a paste-like melted wire which is then subjected to re-treatment through the hot air polishing and cold air shaping apparatus, wherein the extruded material is polished and extruded through spiral hot air, and meanwhile, the hot air is pumped back, and then the stacked material is cooled and shaped by means of cold air generated through semi-conductor refrigeration. Through the hot air for polishing and flatting and the cold air for cooling the material, printing precision is greatly increased, and the material after additive printing is flat and smooth and is free of deformation. A shaped product is more firm.

Description

technical field [0001] The present invention relates to the field of 3D printing manufacturing technology, and more specifically, relates to a multifunctional 3D printing head device. Background technique [0002] At present, when ordinary FDM 3D printers perform additive printing, the nozzle of the print head is a single fixed nozzle, and there is no reprocessing process for the extruded product, which leads to the following disadvantages. [0003] When an ordinary 3D printer is working, the print head is mostly a fixed nozzle. When a fault occurs or the nozzle is blocked, the print head can only be replaced, or a drill bit is inserted into the nozzle to push out the blockage upwards. When the blockage enters the nozzle again, it will Blockage, or remove the print head as a whole and clean it. These operations are cumbersome and bring unnecessary troubles to the 3D printing process. [0004] When ordinary 3D printers work, the extruded accumulations are mostly round lines...
