Four-axis linkage 3D printing device based on fusion deposition principle

Abstract

The invention discloses a four-axis linkage 3D printing device based on the fusion deposition principle, belongs to the field of 3D printing and manufacturing, and relates to the four-axis linkage 3D printing device based on the fusion deposition principle. The printing device is composed of a rack, a printing sprayer assembly, a control assembly, an X-axis drive assembly, a Y-axis drive assembly, a Z-axis drive assembly and an A-axis drive assembly. A shaft sleeve of the A-axis drive assembly can be detached and replaced, a series of shaft sleeves the same in inner diameter but different in outer diameter can be selected, and forming and manufacturing of pipe-shaped structure models different in inner diameter are conveniently achieved. By means of the printing device, a thin-wall pipe net-shaped structure can be conveniently prepared, any auxiliary supporting structure does not need to be additionally arranged in the printing process, the posttreatment and other complex operation processes are simplified, printing materials are saved, and the forming rate and surface quality of test piece printing are effectively improved. The A-axis drive assembly is flexible in control and easy and convenient to mount and dismount, a series of inner diameter test pieces can be formed by replacing the shaft sleeves of different outer diameters, and the four-axis linkage 3D printing device is simple, practical and easy to operate and popularize.

Description

technical field [0001] The invention belongs to the field of 3D printing and manufacturing, and relates to a four-axis linkage 3D printing device based on the principle of fusion deposition. Background technique [0002] In recent years, 3D printing manufacturing technology, as an emerging manufacturing molding technology, has many advantages such as short molding cycle, easy molding of complex and diverse spatial structures, convenient personalized manufacturing, material saving and simple operation, etc., and has developed rapidly. With its unique advantages of "additive manufacturing", it has broad application prospects in the fields of aerospace, mold manufacturing and biomedical engineering, and is especially suitable for personalized manufacturing of medical devices. However, the traditional 3D printing device only has translation in three directions of XYZ, and a large amount of auxiliary support materials need to be added when printing and forming tube network struct...

AI Technical Summary

Problems solved by technology

However, the traditional 3D printing device only has translation in three directions of XYZ, and a large amount of auxiliary support materials need to be added when printing and forming tube network structures such as trachea and tube brackets, which not only reduces the molding efficiency, but also has a cumbersome process of removing support materials. Will result in reduced surface quality and dimensional accuracy
