Post-doctoral position – Research Engineer (14 months) : 3D printed / additive manufacturing calcium phosphate / hydroxyapatite biomaterials: Multiscale Porosity Bone Scaffold FreeForm


Job description

Offer DescriptionPROJECT DESCRIPTION (MP-ScaFF abstract): The cranio-maxillo-facial bone diseases are growing rapidly in recent years, with around 1800 cases/year only due to osteonecrosis in France, as well as the number of accidental fractures requiring surgery. These diseases and traumas can cause critical size defects that are not self-repairable (
1 cm3). The advent and development in the Additive Manufacturing (AM) field allowed for rapid progresses in the production of customized scaffold lattices. However, it is still challenging to find a compromise in terms of good mechanical and biological performances, mainly due to the limitations of existing AM technologies in terms of pores geometries, resolution and dense wall thickness. The MP-ScaFF project focuses on the manufacturing of multiscale porosity and personalized calcium phosphate-based scaffolds through an innovative AM technology, the Dynamic Molding. This process, consisting of 3D printing an extrudable paste into a granular environment, allows for combining the advantages of AM processes as the freeform design for customized implants, and the advantages of the possibility to add sacrificial elements to generate microporosity. It will be possible not only to achieve a multi-scale porosity allowing to mimic the bone microstructure and promote cell proliferation, but also the addition of fully dense parts in the zones needing reinforcements as the screw fixings or external plates. The efficiency of this new implant will be tested in terms of both mechanical (by compression test) and biological (in vitro and in vivo behavior) performance. Furthermore, a simulation model will be developed to for an improved optimisation of scaffold design related to its mechanical behavior. The four partners of this project present the technical clinical skills and the complementarity needed to develop this innovative implant that addresses a public health problem.The recruited Postdoc fellow / Research engineer will work on two main axes:i) He/she will synthetize calcium phosphate raw materials specifically design for Dynamic Molding process (Material extrusion additive manufacturing).ii) He/she will perform microstructural, physico-chemical, and mechanical analysis of printed scaffolds, in order to improve the Dynamic Molding process to enhance final properties of the scaffolds (porosity size and orientation, mechanical properties, Calcium phosphate qualification…). With this aim, he/she will work with academic material scientist and 3Deus Dynamics Company ( ) who will provide Printed scaffold fabrication.Theses experimental work will be carried out at CIRIMAT laboratory where the Postdoc fellow / Research engineer will be hosted by the PPB group, (Phosphates, Pharmacotechnics, Biomaterials).
