AI Technical Summary

Technical Problem

When existing 3D printing equipment manufactures large-sized products, the equipment's moving shaft and external frame become huge, resulting in increased manufacturing difficulty and cost, and the printing platform cannot flexibly select the printing space, resulting in low work efficiency and low material utilization.

Method used

Modular 3D printing methods and equipment are adopted to combine platform modules into multiple platforms according to demand, and utilize the freedom of the robot and track to achieve rapid movement and flexible combination to meet the printing needs of different sizes and batches.

Benefits of technology

The printing of larger sizes or larger batches of products at lower equipment manufacturing costs is achieved, which improves production flexibility and equipment maintenance convenience, reduces costs and improves work efficiency.

Abstract

A modular 3D printing method and device. The modular 3D printing method comprises: driving a first manipulator (11) to move along a first track (21) to a first platform (31) located at one side of the first manipulator (11) and perform powder spreading and printing actions, and driving a second manipulator (12) to move along a second track (22) to a second platform (32) located at one side of the second manipulator (12) and perform powder spreading and printing actions; when complete, rotating the first manipulator (11) and the second manipulator (12) to a third platform (33) located between the manipulators, and driving printing modules (4) on the first manipulator (11) and the second manipulator (12) to cooperate with each other to perform powder spreading and printing actions on the third platform (33). By adopting the present invention, maintenance and replacement are more convenient, and costs are greatly reduced.
