Anti-interference high-precision desktop 3D printer

Abstract

The invention discloses an anti-interference high-precision desktop 3D printer. The anti-interference high-precision desktop 3D printer comprises a rack, an X-axis movement mechanism, a Y-axis movement mechanism, a Z-axis movement mechanism and a remote extruding type wiring mechanism, wherein the rack comprises a horizontally-arranged bottom board and vertically-arranged side boards which are connected with the bottom board; the X-axis movement mechanism comprises a forming base board arranged above the bottom board, a stepping motor X longitudinally installed in a cavity of the bottom board, a screw rod X and a polish rod X, and the screw rod X and the polish rod X are rotationally installed in the cavity of the bottom board and arranged parallel to each other; the Y-axis movement mechanism comprises a U-shaped movable board, a stepping motor Y, a screw rod Y and a polish rod Y, and the screw rod Y and the polish rod Y are rotationally installed on the U-shaped movable board and arranged parallel to each other; and the remote extruding type wiring mechanism comprises a heating nozzle and a wiring mechanism body. The anti-interference high-precision desktop 3D printer has the beneficial effects that material wires with different diameters can be conveyed, disassembly and maintenance are convenient, the printing precision is high, and by adoption of the screw rod and nut transmission mechanism, the anti-interference capacity of the anti-interference high-precision desktop 3D printer is enhanced.

Description

technical field [0001] The invention relates to the technical field of fused deposition manufacturing 3D printing, in particular to an anti-disturbance high-precision desktop 3D printer. Background technique [0002] A 3D printer is a machine that creates real physical objects based on specialized computer files by way of additive creation, hence the name "additive manufacturing". Simply put, a 3D printer is a machine that turns a blueprint into a physical object. The user designs a pattern for it, which is shown to the user in the form of graphics and exists in the microcomputer in the form of a program; the computer works according to this pattern, and through the combination of special materials, a physical object corresponding to the envisioned blueprint will be produced . [0003] At present, 3D printing technology has more than ten kinds of processes. According to the different forming principles, it can be divided into two types: laser laser processing and non-laser...

AI Technical Summary

Problems solved by technology

However, the wire-feeding mechanism that drives the hot-melt material filament is installed on the nozzle, resulting in heavy weight and high inertia of the nozzle, and inaccurate positioning and movement of the nozzle, which further leads to low printing accuracy

Because the nozzle works at high temperature for a long time, it is easy to burn out and has the defect of short service life

In addition, the existing fused deposition printers can only transport material filaments with a constant diameter, and the scope of application is limited, so they are not popularized.
