Abstract: This disclosure provides methods and systems for the additive manufacturing of three-dimensional workpieces using a support fluid build. In one aspect, a method is provided for forming a three-dimensional workpiece, the method comprising dispensing a resin in a liquid state into a container, irradiating at least a portion of the resin layer at the fluid interface with light to polymerize an irradiated portion of the resin layer as a current build layer of the three-dimensional workpiece at the fluid interface, wherein a portion of the three-dimensional workpiece is affixed to a build platform immersed in the support fluid; and advancing the build platform to a next position in the support fluid to submerge the current build layer within the support fluid. The process is repeated to successively build the workpiece in the support fluid.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for fabricating parts from photopolymer resin. In one aspect, a method includes iteratively determining a deviation measurement based on a simulated cured geometry and adjusted target geometry data until the deviation measurement is at or less than a threshold. The simulated cured geometry is determined, based in part, on an inhibition model.
