Abstract

The invention relates to the technical field of laser advanced additive manufacturing, and discloses an additive manufacturing deformation control method for thin-wall partition plate type parts. Themethod comprises the steps that firstly, the placement mode of a part is determined, then process support is added to a thin-wall structure part in the part, the sintering shape part of each layer oflayered slice of the thin-wall structure part is closed into a triangle, importing the process model added with the process support into magics software, manufacturing by adopting an SLM (Selective Laser Melting) process additive manufacturing method, and finally carrying out post-treatment on the obtained part to obtain the product. The problems that thin-wall partition plate type parts are proneto deformation and breakage due to large stress in additive manufacturing can be effectively solved, and the success rate of additive manufacturing of thin-wall structure assemblies is greatly increased.

Description

Technical field [0001] The present application relates to the field of laser advanced additive manufacturing techniques, and more particularly to a method for producing a deformation control method for thin-walled partial parts. Background technique [0002] Additive Manufacturing, AM), also known as 3D printing, is a three-dimensional model that combines computer graphics processing, digital information, and control, laser technology, and material technology, etc., add three-dimensional model, add Support, the resilient sections are two-dimensional patterns, and the powder is filled by a laser beam, and the layer stack is stored, and the three-dimensional solid model is completed. [0003] Many thin-walled components are complex. They use conventional sheet metal, machine, and welding, parts can be achieved, and the laser 3D printing must be used, but the additive manufacturing is a process of continuous cycle, and the thin-walled parts are laser add materials. The thermal stres...
