“What is closed loop technology and why is important to SGLB” Closed loop is important to SGLB because it is expected to automatically correct the machine settings if PrintRite3D detects or indicates that is or will be a flaw or the machine is not operating within the expected norms in order to save a print. Closed loop will also allow some one less than an engineer to operate the machine or machines. Hopefully saving more in costs than what it costs for the engineers and the printing of bad parts. With metal powder inconsistencies and other variables not able to be adjusted. I believe it is an unobtainable goal at least in the near term.
