Abstract
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.Mechanical Engineerin
