Relevance of modeling laser-material interactions in the industrial context

Implementing a virtual production system is challenging due to machine specific interactions, uncertainties and unknowns. The theory of design oriented thinking adapted for manufacturing favours fast iteration in digitised design cycles instead of optimising the model quality in one step. A virtual production system is seen to become a set of ""digital shadows"" emulating relevant properties of the underlying techno-physical systems. Different model reduction techniques are demonstrated resulting in ""digital shadows"" able to generate dense data by millions of runs within acceptable calculation time.
