Missions

The LURPA laboratory of the Farman Institute is looking for a postdoc researcher to carry out characterization and piloting activities on a scanning head for additive manufacturing by laser fusion on a bed of metal powder. The objective is to evaluate the characteristics of the head and its control in order to optimise its operation, programming and process performance. The work will be carried out on an instrumented bench and tests can be carried out on a production machine.

Activities

- Technological and frequency characterization of the scanning head
- Characterization and modeling of the scanning head control (nature of interpolations and servoing)
- Optimization of trajectory programming primitives to limit high-frequency data transfers
- Integration of process parameter variations and synchronisation with laser source control

Skills

• Automatic and control
- Experimentation and validation on experimental platform
- Simulink Modeling
- Programming language (Matlab/Python/C/C++)
- Knowledge of additive manufacturing processes

Work Context

The proposed work is 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 project researchers on related topics.
