ADDITIVE MANUFACTURING IN SITU STRESS RELIEF

摘要

An additive manufacturing process performed by an additive manufacturing machine includes strain gauges that detect stress within a part during fabrication within a defined workspace. When the detected stress is exceeds a desired level the fabrication steps are paused and a stress relieving process is performed within the chamber without moving the part. The additive manufacturing machine includes heaters and coolers for changing the temperature within the chamber to perform the desired stress relieving process in the same space as fabrication is performed. Once it is confirmed that stresses within the part are within acceptable limits the part fabrication process is resumed.
