YEAH - I wish they would give out more PR's. Somebody on this bd once mentioned that they thought the co gives out PR's about every 2 wks. If so, I am waiting!!!

Hi Chris, is this Sigma labs?

"I have worked on two completely different areas of research throughout the summer, immersing myself in the research of non-destructive evaluation, specifically infrared pulse thermography, as well as the area of additive manufacturing.

Quite frequently, as I caused the powerful flash lamps to diffuse heat into a Ceramic Matrix Composite material, a material that GE is ardently developing for use in jet engines, I would notice defects through infrared analysis. Under the non-destructive evaluation umbrella, there are various methods of determining defects, and the particular method depends on the situation/specimen, but I have come to learn that infrared pulse thermography is a brilliant technique. It is a fast, affordable and accurate method of evaluation – I could explain why, but I would not want to bore those who are not interested in the technical tidbits! I have to come to realize that this method of non-destructive evaluation is certainly a pivotal one.
"We have been postulating the possibility of implementing the technique of infrared pulse thermography into the process of 3D printing a specimen. If accomplished, objects would be evaluated for defects during the manufacturing process. Of course, real-time infrared pulse thermography evaluation would not be limited to 3D printing; it could be used for standard machining process as well. However, the quality of a 3D printed part is dependent on many factors, and analyzing the part for defects during the construction of the part could potentially save significant time, money, and even lives. Finding defects in the lab, rather than when the part is already in the field, is a better outcome."
