Exploring Model-Based Engineering Concepts for Additive Manufacturing
Robert R. Lipman, Jeremy S. McFarlane
Robust geometry and tolerance representations are needed in additive manufacturing for precise part specification and interoperability with downstream activities such as manufacturing, inspection, and long-term archiving. A disconnection exists between process-independent part geometry and tolerances, and process-dependent information requirements for additive manufacturing. Existing and emerging standards for part geometry (ASTM AMF, 3MF, ISO 10303 STEP) and tolerances (ASME Y14) contain information related to the additive manufacturing process. Details of the standards will be discussed, how their use and improvement can benefit the additive manufacturing process, and their integration into the model-based engineering paradigm.
