摘要：
A method for producing a component layer-by-layer includes: placing in a loading zone a vat; loading the vat into a build zone of an additive manufacturing apparatus utilizing a vat transport mechanism; executing a build cycle, including: positioning a stage relative to the build surface so as to define a layer increment in the resin; selectively curing a resin contained within the vat using application of radiant energy in a specific pattern so as to define the geometry of a cross-sectional layer of the component; moving the vat and the stage relatively apart so as to separate the component from the build surface; unloading the vat from the build zone into an unloading zone; and repeating the steps of placing, loading, executing the build cycle, and unloading, for a plurality of layers, using a plurality of vats in series, until the component is complete.
