First of all, three-dimensional CT imaging technology can become an effective powder raw material testing method, which can quantitatively count the hollow rate in the powder particles and the corresponding particle size, sphericity and other information.

It can directly observe defects such as internal pores and fractures of the printed product, and can further quantitatively count the overall defect rate of the sample and the characteristic parameters of each defect, such as volume, equivalent diameter, etc., to provide reliable reference data for 3D printing manufacturing process parameters. In addition, the residual powder inside the sample can also be tested and evaluated.

Relying on the function of comparing and analyzing the CAD design model and CT scan data (digital-analog comparison), the deviation between the two is visually expressed in different colors, and the dimensional error is accurately measured and counted.

Through the three-dimensional CT test of the unknown structure sample, the internal structure is obtained, and the CT scan data is formatted to obtain the reverse design file, which can be input into a 3D printer for production of the corresponding product, greatly shortening the manufacturing cycle.
