PrintRite3D makes the closed loop possible, but does not, to my knowledge include a controller. It predicts conditions under which defects might occur... I base that on this statement from Mark Cola in Gary's interview:
Mark Cola: "The work we are doing with our Fortune 100 power generation customer is an early-stage project to demonstrate the proof-of-concept for a new weld repair technology our client has developed. Key to its success is the ability of our IPQA technology to identify key process variables necessary to ensure a quality weld repair. Should our work prove to be effective in identifying key process variables, next steps might entail developing a closed-loop control scheme capable of being integrated into a systems-level solution for deployment globally to the MRO community."
