Thank you, EDMGUY.

The INSPECT closed loop link you used

Do you mean the diagram with controller 14, 16, 17? I got that from Sigma Lab's patent PDF. I didn't draw it but put labels and arrows to follow their explanation. The numbers are from their patent invention descriptions, btw.

Yes, experts systems are not perfect. Cola and Vivek also mentions this. The weakness in IPQA is its training. However, what makes SGLB's closed-loop process unique is higher order control systems. Notice control 16 & database 17 having a feedback loop to controller 14, allowing controller 14 to "learn" from higher functions. Controller 14 can then "better" control the printer. Each instance of anomaly can then be recognized and make the "fingerprinting" process more efficient.

The weakness in IPQA is having a "true fingerprint" in database 17. This is where all parts are compared and matched. So for each layer of the build there must be a "true fingerprint" and this is the most difficult and critical goal to accomplish.

I'm on the same page with you on this. There is a weak link.

I am learning from you're explanations and this is what I enjoy. Thanks, EDMGUY.
