A wax material 3d printer head

Abstract

The invention provides a 3D printer head of wax material, and overcomes the defect that in the prior art, wax material cannot be extruded out smoothly. The 3D printer head comprises an extrusion part, a ventilation part, a heating part and a wire outlet part, wherein the wire outlet part comprises a fixed seat and a line bank; the line bank is fixed at the rear end of the fixed seat; the extrusion part, the ventilation part and the heating part are both mounted on the fixed seat. The 3D printer head adopts a 57 stepper motor, so as to increase the motor torsion and ensure that the thrust of the extrusion part is large enough to extrude out a wax material line with the diameter of 3 mm; a leaf spring is arranged to be used for pressing the wax material and provide enough pressure to ensure that the wax material can be extruded out smoothly; a driving roller made of rubber material replaces a copper gear, so that the wax material is protected from wearing and the copper gear is prevented from scratching the wax material during driving; the aperture of a spray nozzle is 0.8 / 1.0 / 1.2 mm, so that the wax material is prevented from excessive melting at the heating part and more smooth line outlet is ensured.

Description

technical field [0001] The invention relates to the field of printers, in particular to a wax material 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] Existing 3D printers, whose machine head is composed of motor, axial flow fan, transmission gear, nozzle, etc., have the following disadvantages: the torque of the motor is not enough, and the wax material cannot be extruded; the gear and guide wheel will wear the wax material, result...
