ADDITIVE MANUFACTURING MANAGEMENT OF LARGE PART BUILD MASS

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.
