Manufacturable ELements (MELs) are proposed as an intermediate representation to support Design For Additive Manufacturing (DFAM) and process planning. MELs are constructed to relate design features and geometric regions to manufacturing operations that are suitable to fabricate those features or regions. Such intermediate representations provide a validated parametric model that aids in the construction of as-fabricated part models for both engineering analysis and process planning. Viewed differently, MELs contain information with which designers can explore process-structure-property relationships of design features that capture manufacturing process characteristics. Examples are provided for vat photopolymerization and material extrusion processes.
