The invention provides an extrusion spraying head of an electromagnetic induction heating type 3D printer. The extrusion spraying head comprises a combined type spraying head body, a heating device, a cooling device, a material conveying device and a protective gas channel, wherein an annular metal block is arranged outside a ceramic spraying head of the combined type spraying head body; the heating device is an electromagnetic induction heating device and comprises an electromagnetic induction coil, a coil fixing frame, a supporting frame, a shielding cover I and a shielding cover II; a lead-out wire of the electromagnetic induction coil is mounted on the supporting frame through the coil fixing frame; the electromagnetic induction coil sleeves outside the annular block; the shielding cover I and the shielding cover II are connected to and cover on the outside of the electromagnetic induction coil; the shielding cover I is mounted on the supporting frame. The extrusion spraying head of the electromagnetic induction heating type 3D printer solves the problems of discontinuous wire leading-out of a metal 3D printer based on an FDM technology and blockage of a spraying head assembly; a high-temperature-resistant and heat-insulation ceramic ring can effectively prevent heat of the spraying head from being transmitted to a throat pipe, thus preventing consumables from being softened too early; due to electromagnetic induction heating, the melting speed and the printing efficiency of metal wires are improved.
Description
technical field [0001] The invention relates to a 3D printing nozzle, in particular to a 3D printer extrusion nozzle using metal wire as a consumable. Background technique [0002] 3D printer, also known as three-dimensional printer, is a machine of rapid prototyping technology. It is a technology based on a digital model file and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacture of some products. The technology can be used in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, and many other fields. [0003] At present, relatively mature metal 3D printing technologies include selected laser sintering techno...
