Title:
ADDITIVE MANUFACTURING METHOD FOR FUNCTIONALLY GRADED MATERIAL
Document Type and Number:
Japanese Patent JP2020116943
Kind Code:
A
Abstract:
To provide a method for producing a functionally graded component layer-by-layer.SOLUTION: A method for producing a functionally graded component layer-by-layer includes the steps of: 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 a 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; and repeating at least the steps of positioning and selectively curing for a plurality of layers, until the component is complete.SELECTED DRAWING: Figure 1
