Biography

Sylvain Gouttebroze is a Senior Research Scientist at SINTEF Industry (Metal Production and Processing), working at the interface of microstructure and manufacturing modelling, semantic interoperability, and data-centric process analysis. His recent co-authored work includes an integrated computational framework for optimizing microstructure in metal additive manufacturing (2025), as well as contributions to SOFC electrode modelling and broader process simulation studies. He has played an active role in advancing semantic standards for manufacturing, co-authoring “Toward Semantic Standard and Process Ontology for Additive Manufacturing” (2024). His research combines micro- and macroscale modelling approaches to study aluminium precipitation, duplex stainless-steel additive manufacturing, and cast-iron inoculation, using finite-element, continuum, and phase-field methods. Earlier in his career, he investigated solidification and macrosegregation phenomena—such as steel 3D-FEM modelling and silicon-ingot thermo-mechanics—demonstrating a long-standing expertise in materials processing, simulation, and digitalisation of manufacturing knowledge.

70 Effect of the deposition pattern on the microstructure for LPBF of duplex stainless steel

We present an extension of the integral multiscale computational framework for the optimization of the microstructure in metal additive manufacturing. We focus now on the effect of the laser scanning pattern on the microstructure. In addition, we test the platform with another macroscale module based on Simufact Welding and for process parameters representative of LPBF instead of DED.

The laser scanning of a surface with different patterns without building a multi-layer domain is simulated. Results show that the microstructure is very different from previous DED results and that significant improvements could be achieved by optimization of the pattern and possible laser heat treatment.
