METHOD OF COMPENSATING FOR SINTERING WARPAGE DUE TO POWDER SPREADING DENSITY VARIATIONS IN BINDER JET 3D PRINTING
A method of compensating for sintering warpage due to powder spreading density variations in binder jetting additive manufacturing, including receiving an initial design file defining an object geometry, representing the object geometry as a part mesh and filling the mesh with a grid of voxels to create a voxel grid, each voxel having at least one shrinkage coefficient. For each voxel, determining a distortion factor caused by a powder density variation induced during a powder spreading process and adjusting the at shrinkage coefficient of each voxel according to its respective distortion factor. Next, a shrinkage of the grid of voxels is simulated according to a sintering process. A negative compensation is applied to the voxel grid, according to the simulated shrinkage of the grid of voxels, to form a compensated voxel grid. Lastly, the change in the voxel grid is mapped to the compensated voxel grid onto the part mesh to create a pre-processed compensated part mesh.
METHOD OF COMPENSATING FOR SHRINKAGE AND DISTORTION USING SCANS
A method of compensating for shrinking and distortion of an object resulting from a manufacturing process. A scan is performed of an object following a manufacturing process to produce scan data. The scan data is aligned to a part mesh of the object. The part mesh is adjusted to substantially coincide with the scan data by moving part mesh vertices. Delta vectors are computed by subtracting initial part mesh vertex positions from final part mesh vertex positions. The inverse of the delta vectors are applied to the preprocessed part mesh to give a scan adjusted pre-processed shape.
