Missions
The postdoctoral researcher will work on the formulation and characterization of 3D-printable dental resins based on polyurethane methacrylate. Main tasks include:
• Formulation development using monomers and various diluents (DoE).
• Rheological characterization for DLP compatibility.
• UV curing kinetics via rheology and FTIR.
• Mechanical property evaluation.
• Incorporation of functional fillers (to be defined).
• Collaboration with academic and industrial partners in the CmaDENT project
Activités
The ANR CmaDENT project aims to develop innovative dental materials with mechanical property gradients, mimicking natural tooth structure, using additive manufacturing. The goal is to design photopolymerizable composite resins compatible with Digital Light Processing (DLP) 3D printing, for clinical and educational applications
Compétences
PROFILE AND SKILLS
• PhD in polymer chemistry, chemical engineering, materials science or related field.
• Expertise in resin formulation, rheology, FTIR spectroscopy; experience in 3D printing is a plus.
• Autonomy, rigor, teamwork and strong written and oral communication skills in French and English.
Contexte de travail
The research will contribute to the ANR project “Design of Dental Materials with Property Gradients through Additive Manufacturing” (CMADENT). The objective of the CMADENT project is to revolutionize CAD/CAM by replacing the current manufacturing process — which involves machining ceramic or composite blocks — with an additive manufacturing technique (resin-based 3D printing). This approach will also help reduce material waste. Designing prosthetic components capable of mimicking the natural property gradients of teeth requires parallel development of both the 3D printing technology and the photopolymerizable dental composite resins. The project will be carried out in collaboration with laboratories from complementary disciplines (hospital-based dental practitioners, mechanical engineers, and computational scientists), as well as with a manufacturer of dental biomaterials, with whom the candidate will be expected to interact.
Le poste se situe dans un secteur relevant de la protection du potentiel scientifique et technique (PPST), et nécessite donc, conformément à la réglementation, que votre arrivée soit autorisée par l'autorité compétente du MESR.
