Abstract
A system and method for improving the production of objects with fully defined CAD models by generating CAD slice files from the native CAD geometries for use by AM machines. An electronic processing element receives the CAD model having a native and/or neutral format with metadata, determines a desired resolution, slices the CAD model to create the slice files having a slice format (e.g., point, edge, surface, volume) and retaining the metadata, and evaluates the slice files to determine whether the resolution has been achieved. If so, the slice files are sent to the AM machine. If not, a new desired resolution is determined and the CAD model is re-sliced, which may include combining the slice files to regenerate the CAD model. A support structure for the object may be analyzed, and if distortion is predicted, a modified CAD model may be created and sliced to create modified slice files.
