Multi-platform efficient material extrusion additive manufacturing equipment and block printing method

Abstract

The invention discloses multi-platform efficient material extrusion additive manufacturing equipment and a block printing method. The equipment comprises a base, four independent printing platforms are arranged on the base, and a guide groove is formed at the side edge of the base and used for being connected with a first support and enabling the first support to rotate around the base along the guide groove. A laser capable of sliding back and forth along the first support is arranged on the first support. A second support is arranged above the base and can move up and down along supporting columns, and a laser capable of sliding along the second support is arranged on the second support. By using the multiple printing platforms, the printing efficiency is greatly improved. According to the block printing method, use of most supports can be avoided, then printing materials can be saved, the printing speed can be increased, the post-processing step of removing the supports is omitted, and the surface quality of a workpiece is improved. In addition, different printing materials and different colors can be applied to different platforms through multi-platform block printing, so that the workpiece can be more attractive and rich in creativity.

Description

Technical field [0001] The present invention belongs to the technical field of additive manufacturing, and more particularly to a multi-platform high-efficiency material extrusion adding material manufacturing apparatus and block printing method. Background technique [0002] 3D printing belongs to the emerging technologies in the fast-molding field, and each developed country uses it as a strategic development. It is widely used in aerospace, automotive manufacturing, biomedical. Compared to traditional manufacturing processes, the technology integrates multiple techniques such as digital control, new materials, and computer aided design, saves the product mold processing and manufacturing link, shortens production cycle, increase productivity, and reduce cost investment. 3D printing techniques can be divided into many types, with the most typical type of material extrusion molding technique: FUSED Deposition Modeling, FDM) is a 3D printing technology that operates is the most s...

AI Technical Summary

Problems solved by technology

In short, although the use of water-soluble support materials can solve the support problem, it will also bring some other troubles in equipment or materials, and the cost of materials will increase, and the molding time will be longer

[0005]3. It is difficult for FDM molding equipment to achieve multi-color and multi-material mixed printing

The most common FDM printers on the market are single-nozzle printers. This type of printer has high precision and is easy to maintain, but it is difficult to remove the inner cavity support, and it can basically only print single-color single-material parts.

In order to be able to print multi-color and multi-material model parts, one method is to use multi-nozzles, but multi-nozzles will increase the cost of the equipment, and the positioning accuracy of the equipment is poor, the maintenance is complicated, and the failure rate is high

Another method is to use a single-nozzle multi-extruder. This method has high precision and can achieve gradient color printing, but its heating module structure is very complicated, and it cannot print patterns with distinct colors.

[0006]The above three reasons clearly reflect the limitations of the existing FDM printing equipment in the actual printing process, and these reasons have seriously affected the development of FDM printing equipment and popularity
