A robot laser 3D printing system and method

Abstract

The present invention relates to a robot laser 3D printing system and method, which uses a mechanical arm to drive a laser printing head unit to perform 3D printing. Wrist joint, robot wrist, connection plate, protective gas supply pipeline, powder supply pipeline connected to the powder silo, the connection plate is connected to the laser print head unit, the connection plate drives the laser print head unit to rotate, the protective gas supply pipeline, The powder supply pipeline is fixed on the upper arm and the small arm through the fixing ring; the shielding gas supply pipeline and the end of the powder supply pipeline are connected with the laser printing head unit. The advantage is that it can directly process and manufacture metal parts of any shape, especially stainless steel alloy parts, which greatly improves the processing and manufacturing efficiency of metal parts with complex shapes, especially stainless steel alloy parts. The metal powder used is directly sprayed according to the shape of the part, the remaining powder is small, and it can be recycled and reused.

Description

technical field [0001] The invention relates to the field of 3D metal printing, in particular to a robot laser 3D printing system and method. Background technique [0002] 3D printing is a rapid prototyping technology, also known as rapid prototyping (RPM) technology, which was born in the late 1980s. It is an efficient manufacturing technology based on the direct sintering and accumulation method of materials. A major innovation. It integrates mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, numerical control technology, material science, and laser technology, and can automatically, directly, quickly and accurately transform design ideas into prototypes with certain functions or directly manufacture parts , so as to provide a high-efficiency and low-cost solution for the production of prototype parts and the verification of new design ideas. That is, rapid prototyping technology is to use the data of three-dimensional CAD to a...
