Description

Technical field [0001] BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to the technical field of material processing, and Background technique [0002] The laser additive manufacturing technique is a technique such as a powder, such as a powder, a technique, such as a selective laser sintering technology, and sterective laser sintering techniques, including selective laser sintering techniques, including selective laser sintering techniques, including selective laser sintering technologies and Stereolithography. The beam stability and spot quality of the laser are important factors related to precision manufacturing. In order to obtain a more uniform light intensity distribution on the laser projection surface, a circular spot or an elliptical spot (referred to herein is referred to as "spot spot") is advantageous, and the size of the spot is small. Therefore, laser additive manufacturing techniques are often used to make small batch or micro componen...

AI Technical Summary

Problems solved by technology

It can be seen that the laser additive technology has low efficiency, high cost and long cycle when manufacturing large components, and will cause thermal deformation and thermal stress of the product

The thermal deformation and thermal stress accumulated during the long-term additive manufacturing process will greatly limit the application of laser as a forming heat source or trigger energy source in additive manufacturing technology, especially for large-scale components.
