A method to improve the success rate of 3D printing thin-walled metal components

Abstract

The invention discloses a method for improving the success rate of 3D printing thin-walled metal components, which includes the following steps: 1) performing early software processing on the digital model of the thin-walled metal components, adjusting the position of the thin-walled metal components in the equipment forming cabin, ensuring Thin-walled metal components can be printed; 2) Place and optimize the digital models of thin-walled metal components that meet the above requirements; 3D printing equipment, preparatory work for printing equipment in the early stage, and start printing through 3D printing technology after the preparation work is completed; 4) After printing is completed, take out the thin-walled metal components for subsequent processing, and finally complete the delivery of thin-walled metal components. The present invention can give full play to the printing size correction function of the scraper through the secondary optimization of the placement position of the thin-walled metal components required by the basic placement, reduce the risk of scraper jamming, and improve the printing success rate of the thin-walled metal components.

Description

technical field [0001] The invention relates to the technical field of laser advanced additive manufacturing, and specifically refers to a method for improving the success rate of 3D printing thin-walled metal components. Background technique [0002] The additive manufacturing process (commonly known as 3D printing) is widely used in aviation, aerospace, etc. due to its advantages of high flexibility, short process, integrated forming of complex structures, small heat-affected area, high material utilization rate, high degree of freedom of operation, no pollution, and net shape. The field of manufacturing complex metal components has been applied on a large scale. [0003] However, with the continuous improvement of design-manufacturing requirements, the requirements for ultra-fine and complex structural components manufactured by additive manufacturing processes have also increased. In particular, there is an increasing demand for 3D printing of thin-walled metal componen...

AI Technical Summary

Problems solved by technology

[0004] At present, the printing and manufacturing of complex thin-walled metal components is not only limited by the forming size of the equipment, but also the printing and manufacturing process is not yet mature, resulting in an increased probability of printing failure and repeated failures. It takes multiple iterations to find the best solution. This situation greatly increases the cost of equipment, raw materials and labor, which seriously restricts the development of this technology

[0005] The most critical reason for the failure of thin-walled metal components to print is the inability to accurately control their warping deformation during the printing process

Due to the high strength of metal materials, when deformation occurs due to heat concentration during the printing process, the deformed part is prone to jamming of the scraper, which can easily cause damage to the scraper and components, and eventually make the printing invalid
