Novel precise 3D printer

Abstract

The invention relates to the technical field of fast designing and forming machines, in particular to a novel precise 3D printer. The novel precise 3D printer comprises a supporting mechanism, a feeding mechanism, a first-level movement mechanism, a second-level movement mechanism and a spray head mechanism. The supporting mechanism is used for supporting the whole 3D printer and a formed product. The feeding mechanism is used for storing and providing wire filler needed by the 3D printer for printing the product. The first-level movement mechanism and the second-level movement mechanism are used for driving a spray head to carry out printing movement. The spray head mechanism is used for melting and extruding the wire filler and can cool printing materials at the same time. According to the novel precise 3D printer, it can be selected that only the first-level movement mechanism works and can be used for printing products with small sizes and low precise requirements, only the second-level movement mechanism works and can be used for printing products with small printing sizes and high precision or fine structures on the surfaces of products, and when the first-level movement mechanism and the second-level movement mechanism work in cooperation, the first-level movement mechanism is used for achieving rough positioning, and the second-level movement mechanism is used for carrying out precise printing work.

Description

technical field [0001] The invention relates to the technical field of designing rapid prototyping machines, specifically a novel precision 3D printer. Background technique [0002] 3D printing technology is an advanced manufacturing technology that integrates computer science, optics, material science and other disciplines, and accumulates 3D CAD models of parts into parts with certain structures and functions through manufacturing equipment. [0003] Existing 3D printers are generally unable to adjust the molding accuracy and printing speed of the 3D printer according to different products or when printing different parts of the product, which restricts the promotion and application of 3D printers. [0004] Fusion extrusion molding (FDM) 3D printers are small in appearance and low in cost, but the existing fusion extrusion molding (FDM) 3D printers cannot solve the problem of wire blocking during printing well. [0005] During the printing process of the melt extrusion mo...

AI Technical Summary

Problems solved by technology

[0003] Existing 3D printers are generally unable to adjust the molding accuracy and printing speed of the 3D printer according to different products or when printing different parts of the product, which restricts the promotion and application of 3D printers

[0004] Fusion extrusion molding (FDM) 3D printers are small in appearance and low in cost, but the existing fusion extrusion molding (FDM) 3D printers fail to solve the problem of wire blocking during printing

[0005] During the printing process of the melt extrusion molding (FDM) 3D printer, as the raw material is extruded, it needs to be cooled at the same time. The existing cooling device generally uses a fan. The vibration of the nozzle affects the uniformity of the extrusion device and the quality of the three-dimensional model
