Abstract:
A method of generating a distortion-compensated geometry for a workpiece includes generating a green body part geometry for the workpiece, discretizing the green body part geometry into a green body part mesh and performing a first sintering analysis on the green body part mesh to generate a post-sintering mesh based on the green body part mesh, the post-sintering mesh including a plurality of post-sintering mesh nodes. The method also includes co-registering the post-sintering mesh and a model mesh having a geometry corresponding to the three-dimensional model, the model mesh including a plurality of model mesh nodes. For each of the plurality of post-sintering mesh nodes, a displacement between a post-sintering mesh node and a corresponding model mesh nodes is determined, and the green body mesh may be adjusted based on the displacement to generate the distortion-compensated geometry.
