Abstract
Advanced modelling of additive manufacturing (AM) often requires combining models from multiple scales and diverse physical domains. Thus, constructing a modelling workflow that describes the process can be complex. Moreover, modelling is just one facet of the innovation process; it must be integrated with practices, experimental work, and characterisation. Efficiently communicating and exchanging data among different stakeholders can quickly pose challenges. This requires the unambiguous and consistent use of terms and definitions for various concepts in each technological field. International standards provide a structured source for these technical terms and definitions. For AM, the internationally recognised source for terms and definitions is the ISO/ASTM 52900 standard, titled “Additive manufacturing – General principles – Fundamentals and vocabulary”. Using the AM terminology standard as the basis for the ontology will significantly ease the integration of AM processes into industrial manufacturing systems. Furthermore, to enhance relevance to material science, these concepts will be linked to a microstructure domain ontology as well as to the top- and middle-level EMMO ontology. The conceptualisation and application of the ontologies will be illustrated through simple examples of process and material modelling.
