Missions

The LURPA laboratory of the Farman Institute is looking for a postdoc researcher to carry out experimental validation activities of a 3D numerical simulation model of thermal transfer along scanning paths in metal additive manufacturing. This model allows us to control the parameters of the SLM machine to respect thermal constraints. The aim is to optimize these parameters with regard to productivity and part quality. It will be necessary to instrument the machine on the one hand and to analyze characterization specimens manufactured with different types of scanning paths and manufacturing parameters.

Activities

• Implementation of the 3D simulation model in Matlab.
• Definition and execution of a design of experiment for validation of the model through:
o in-situ measurements using a thermal camera
o characterization of the geometry of melted areas on samples
• Analysis of the results
• Relocating the 3D simulation model

Skills

• Thermal transfers in additive manufacturing
• Experimentation and validation on an experimental platform
• Data processing and formatting
• Matlab Programming

Work Context

The proposed works are part of the SOFIA project (SOlutions pour la Fabrication Industrielle Additive métallique) whose consortium is composed of 7 industrial groups, 2 SMEs and 8 laboratories. The work will mainly be carried out at the ENS Paris-Saclay and will be the subject of exchanges with other researchers in the project on related topics.
