Thanks for this post. Looks like the patent for Thermal. That is sweet!!! Thermal control is a very important part of ensuring part quality.

Methods are needed for in-process monitoring and closed-loop feedback to help improve consistency, repeatability, and uniformity across machines. In situ sensors are an area that holds potential for providing nondestructive evaluation and enabling early defect detection, particularly related to thermal control.

In additive manufacturing, the direction of the beam or the processing direction can induce thermal stresses in the part, impacting the precision of the final part. The resolution of the beam and/or particles also influence heat transfer and internal stresses, thereby influencing the integrity of the final part.

I hope this filing means they are closing in on development of their thermal product. Mark is working hard to stay a step ahead and remain the IPQA leader. This will serve SGLB well for the next several years.
