Digitalization in materials science is an emerging field of research that opens up many new opportunities, e.g. in materials engineering. In particular, if large data sets of many experiments can be evaluated with the help of artificial intelligence. The more information about production, characterization, etc. can be recorded and processed in a machine-readable form, the greater the additional benefit.
A particular challenge is to transfer information that would be recorded in the classic lab book with a simple sketch into a machine-readable form, like the exact position of a measurement. However, this data is important for the evaluation of the experiment.
The application considered is the 3D printing of conductive nanosilver and the determination of the anisotropic electrical conductivity. We semantically describe printing process, environment parameters and characterization in an ontology to investigate dependencies of the conductivity. Therefore, we developed a template-based ontology engineering approach with OTTR templates, to add an abstraction layer to the common but very technical ontology engineering processes.
