Abstract

The invention provides a 3D printer head for solving the problems that the 3D printer head in the prior art has a complex structure, is easy to cause material blockage and leakage and has poor cooling effect. The 3D printer head comprises an extruding part, a ventilation part, a heating part and a line outgoing part, wherein the line outgoing part comprises a fixed base and a line bank, the line bank is arranged at the rear end of the fixed base, and the extruding part, a ventilation part and the heating part are all arranged on the fixed base; the ventilation part adopts an interior-drafting type axial fan, air blown by the interior-drafting type axial fan is enabled to flow into a stepping motor at the extruding part, so as to lower the temperature of the stepping motor, ensure the stepping motor to work normally and prolong the life of the stepping motor; besides, downward airflows can directly cool the 3D printer head during printing, use of double fans is avoided; the design of the ventilating channel can effectively reduce the volume and the weight of the 3D printer head.

Description

technical field [0001] The invention relates to the field of printers, in particular to a 3D printer head. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files 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. In particular, some high-value applications (such as hip joints or teeth, or some aircraft parts) already have parts printed using this technology. [0003] The existing 3D printers, whose machine head is composed of motors, double fans, heat sinks, printing heads, etc., have the following disadvantages: using domestically produced motors, the torque is not enough, the wire feeding is unstable, the life is short, and the weight and volume are large; ...
