Abstract

The invention relates to a 3D laser printing system and method based on a robot. A mechanical arm is utilized for driving a laser printing head unit for 3D printing, and comprises a machine base, a horizontal rotating disc, an arm joint, an upper arm, an elbow joint, a lower arm, a wrist joint, a robot wrist, a connecting disc, a protection gas supply pipeline, and a powder supply pipeline connected with a powder stock bin. The connecting disc is connected with the laser printing head unit, the connecting disc drives the laser printing head unit to rotate, and the protection gas supply pipeline and the powder supply pipeline are fixed to the upper arm and the lower arm through fixing rings. The end of the protection gas supply pipeline and the end of the powder supply pipeline are connected with the laser printing head unit. The 3D laser printing system and method have the advantages that metal parts, especially stainless steel alloy parts, in any shape can be directly machined and manufactured, and the machining and manufacturing efficiency of the metal parts, especially the stainless steel alloy parts, in the complex shapes is greatly improved. Adopted metal powder is directly sprayed according to the shapes of the parts, and little powder is left, and 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...
