Testing of 3D Printed Metals
Layer-by-Layer Non-Destructive Testing of Metal 3D Printed Objects
This technology is being developed to allow for the non-destructive testing of metal printed parts layer-by-layer during the build process.
About
This technology is being developed to allow for the non-destructive testing of metal printed parts layer-by-layer during the build process. This would allow for correction of voids while it is being printed, instead of printing a new part to replace it.
Key Benefits
IR thermography can detect certain defects, but is less refined spatially. The benefit of this periodic thermoreflectance based technique is a sensitivity to just a layer into the material, by controlling the frequency of the laser input. This system can use the existing laser used to melt material.
