A multi-material 3D printer

Abstract

The invention relates to a multi-material 3D printer, comprising a frame, a bottom plate, a Z-axis translation mechanism, a printing platform, an oblique drawing mechanism, a mounting plate and at least two material holding mechanisms; the bottom plate is fixedly mounted on the frame; the The Z-axis translation mechanism is supported on the bottom plate and can move relative to the bottom plate; an optical machine is installed on the Z-axis translation mechanism, and the light machine can move to the bottom of any material holding mechanism along with the Z-axis translation mechanism; the printing platform is installed on On the Z-axis translation mechanism, it can lift up and down and move horizontally; the bottom end of the oblique pulling mechanism is installed on the bottom plate, and the top end is connected to the mounting plate, which can drive the mounting plate to turn over; the material holding mechanism is arranged side by side on the mounting plate ; The printing platform can be translated to the top of each material holding mechanism along the arrangement direction of the material holding mechanism, so as to realize multi-material printing by using different printing materials in each material holding mechanism. The invention can realize the printing of various materials, and the printing demoulding is fast, and can effectively solve the problem that the printing materials cannot be printed.

Description

【Technical field】 [0001] The invention relates to a printer, in particular to a multi-material 3D printer, which belongs to the technical field of 3D printing. 【Background technique】 [0002] A 3D printer, also known as a three-dimensional printer, is a machine that uses cumulative manufacturing technology (ie, rapid prototyping technology). Its principle is to put data and raw materials into the 3D printer, and the machine builds the product layer by layer according to the program. [0003] The prior art 3D printer is shown in the People's Republic of China Utility Model Patent No. 201720190250.5. However, the above printers often have the following defects in the actual use process: [0004] 1. It can only print one material, and cannot support multi-material printing. There is a problem of a single printing material, and it cannot meet the needs of one print that can print multiple materials. [0005] 2. The height of the liquid tank containing the printing solution can...

AI Technical Summary

Problems solved by technology

[0004] 1. It can only print one material and cannot support multi-material printing. There is a problem of single printing material, which cannot meet the needs of printing multiple materials in one print

[0005] 2. The height of the liquid tank containing the printing solution cannot be adjusted, and thus the distance between the liquid level of the printing material and the printing platform cannot be adjusted, and there is a problem that the printing material cannot be printed

[0006] 3. When the printing material has a high viscosity, the printing platform is slow and difficult to demould, and the demoulding efficiency is low, which affects the printing speed
