摘要： An additive manufacturing machine includes a base plate for supporting fabrication of a desired part geometry. The base plate includes a support portion defined based on the desired part geometry and an open region that includes a plurality of openings surrounding the support portion. A material applicator deposits material onto the base plate and an energy directing device directs energy to form the deposited material into a desired part geometry. The additive manufacturing machine manages large amounts of material required for fabricating the part by defining a boundary surrounding a periphery of a desired part geometry and forming a retaining wall along the defined boundary and the desired part geometry to retain excess material between the formed wall and the part. Excess material outside of the retaining wall falls through the open area below the base plate and is reclaimed for reuse.

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.

摘要： An additive manufacturing process includes the steps of measuring a parameter of a part supported within a workspace after a heat treat or other stress relieving process. The measured parameter being a part characteristic that is desired to be within a desired range prior to proceeding with an additional fabrication process. The process further includes the step of applying at least one additional layer on the part based on the measured parameter to adjust the measured parameter to within the desired range.
