Post-Doc - Rheological Behavior of Silicone for Additive Manufacturing

Description :
Context :
The project RAMSAI (Robotized Additive Manufacturing for Silicone assisted by an Artificial Intelligence) funded by the French National Research Agency (ANR) gathers 4 university laboratories : ICube (Manager, Strasbourg), PIMM (ENSAM-Paris) and IMP and ICBMS (Lyon). RAMSAI aims at providing a new production tool for additive manufacturing, particularly by Liquid Modeling Deposition (LMD) for silicone parts, offering better quality of 3D objects using artificial intelligence techniques.
In this framework, a postdoctoral position of 24 months is offered at the IMP laboratory (Ingénierie des Matériaux Polymères, to start in February 2023. The IMP Laboratory has a singular position at national and international levels by integrating various scientific skills related to polymer science (Macromolecular chemistry, Rheology, Processing and Physics) in order to the establishment of structure-properties relationships.

Postdoctoral subject :
The objectives of the 24 months postdoctoral internship will be mainly :
1) Identifying the key examples of available silicones covering the material properties window which govern the LDM,
2) Deeply characterizing their rheological behaviors and extracting relevant parameters (viscoelastic behavior, yield stress, temperature effect, solidification kinetics…)
3) Modeling the behavior to predict the flow in the nozzle, shape stability after the die exit, layers welding and curing kinetics.
4) Collecting data from LDM experiments and streamlining it into a format readily used by AI-based monitoring and control.

This internship will take place mainly at the IMP laboratory, under the direction of René Fulchiron, and, to a lesser extent, at ICBMS laboratory (Institut de Chimie et de Biochimie Moléculaires et Supramoléculaires, Lyon) within the world-renowned 3d.FAB platform.

Profile :
The candidate should possess a PhD in polymer science with knowledge in rheology from both experimental and modeling aspects. Experience in additive manufacturing will be an advantage.
