Abstract:
A method for producing a functionally graded component layer-by-layer includes: depositing radiant-energy-curable resin on a build surface defined by a resin support, the resin containing filler including at least two groups of particles with different physical properties; allowing the filler to settle such that the groups of particles separate from each other, defining at least two regions within the resin; positioning a stage relative to the build surface so as to define a layer increment in the resin; selectively curing the resin using an radiant energy applied in a specific pattern so as to define the geometry of a cross-sectional layer of the component; moving the build surface and the stage relatively apart so as to separate the component from the build surface; repeating at least the steps of positioning and selectively curing for a plurality of layers, until the component is complete.
