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

Embodiment Construction

[0014] The present invention will be further described in detail through specific embodiments in conjunction with the accompanying drawings and technical solutions.

[0015] attached figure 1 , attached figure 2 It is a schematic diagram of the overall structure of the 3D printing device, with image 3 It is a schematic diagram of the structure of the A-axis device of the 3D printing device. As shown in the figure, the printing device is composed of a frame, a printing nozzle 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; the control assembly coordinates and controls the X-axis, Y-axis, Z-axis The axis drives the movement of the assembly, so as to realize the horizontal movement of the print head assembly in the X and Y directions and the up and down movement in the Z direction. The surface of the A-axis can be used as a printing working platform to achieve continuous rotation in the d...

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...
