Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, in particular to a support frame for an X-ray irradiation table. Background Art

[0002] An X-ray flaw detector is used to detect whether the metal powder inside a 3D printed part is cleaned up. The X-ray flaw detector in the prior art includes an X-ray irradiation table, and the X-ray irradiation table can only rotate around a vertical axis. In the prior art, as Figure 1 shown, when the 3D printed part has not been separated from the 3D printing substrate, the 3D printing substrate and the 3D printed part are placed on the X-ray irradiation table together, and the residual metal powder inside the 3D printed part is deposited at the bottom of the 3D printed part. Since the 3D printing substrate and the 3D printed part can only rotate around the vertical axis with the X-ray irradiation table and the residual metal powder is deposited at the bottom of the 3D printed part, it is very difficult to accurately judge whether the object irradiated by the X-ray is the residual metal powder or the structural feature of the 3D printed part itself. If subsequent processing is carried out when there is still uncleaned residual metal powder inside the 3D printed part, it is easy to cause the 3D printed part to be scrapped.
