Design of components with critical part geometry for testing of new manufacturing processes

The AMRC Design and Prototyping Group (DPG) outlines a method for streamlining part family verification for AM processes developed as part of the Horizon 2020 Symbionica project.

Additive manufacture (AM) can offer advantages when compared to traditional machining processes. The AM process can produce components with complex form, providing flexibility that allows frequent changes to component design and offers reduced lead times for certain component geometries.

Deviations from CAD nominal geometry can occur when producing components using AM; but the AMRC has trialled methods for correcting small build deformations in AM components, with good results. While correction methods work well for single components, many thousands of unique combinations of variables may exist for a single part family, and traditionally each unique combination would require verification using the AM process.
