X線CTによる金属AM技術の品質保証方法の検討

抄録

There are various technical issues in aiming at the productization of metal additive manufacturing parts. One of them is the issue of quality assurance. In particularly, it is necessary to thoroughly consider the inspection method and assurance method for internal structures and complex shapes.

The X-ray CT equipment is one of the effective means to solve this problem. The X-ray CT equipment can confirm the internal structure and internal defects of the product in a non-destructive manner. In recent years, various developments of Xray CT have progressed, and their utilization methods are increasing. Various utilization methods are also being examined in metal additive manufacturing. In this talk, we will summarize and report on the utilization method of X-ray CT equipment and the current issues in metal additive manufacturing.
