Formation and Control of Pore Defects in Metal 3D Printing

Abstract

: In the printing process of 3D technology, the porosity defects caused by relevant reasons are often serious. For this, it is necessary to grasp its formation mechanism and do a good job of quality control in the application process of 3D printing technology, which is of great significance for the wide application of 3D printing technology. This paper gives a brief description of 3D printing technology, focusing on the formation mechanism and control measures of pore defects in metal 3D printing.
