Cybernet developed an inline quality control sensing and and control system to be applied to In-Space Manufactured (ISM) additive manufactured parts. The approach leverages and productizes technology disclosed by the Marshall Space Flight Center in reference number MFS-TOPS-70 case number MFS-33013-2, a method that determines geometric differences (flaws) between the designed model and the printed part/component by employing IR cameras to collect accurate temperature data that can be validated against valid thermal models. We add a mature but improved NIR optical measurement to implement an additional function on the moving AM extrusion head. We then use the 3D data acquired by this embedded scanning sensor to (a) provide dimensional verification of part geometry after each deposition pass, and (b) when employed real time to modify machine control – likely requiring modification of the AM machine’s X, Y, Z, and feed rate controlling mechanisms that have to be different depending on ambient conditions (temp, humidity, and gravity) and deposited materials (plastic and plastic emulsion material differences).
