Description Bioabsorbable metallic scaffolds and implants constitute an important area of research in tissue engineering and regenerative medicine.
In contrast with other biomaterials used as scaffolds, such as hydrogels, they represent the only family of materials that can generate a temporary platform to support and ideally induce the growth or healing of a biological tissue, while exhibiting sufficient mechanical properties during the process in a number of applications, such as bone regeneration or cardiovascular stents.
This project will study the processability of Zn-based alloys for biomedical applications using in-situ X-ray tomography during LPBF process.
The focus is to understand the fundamental mechanisms in this particular material with low melting and boiling points where the generated fumes post a problem for the processability of the material.
The effect of metal vapor on the melt-pool and defectology characteristic as the material is printed will be investigated via quantitative electron and X-ray microscopy.
The effect of reused powder on the printed material microstructure is of critical relevance to obtain microstructures suitable for biomedical applications, as well as for process sustainability.
During the printing process high speed visual imaging will be used to correlate and compare the effect of printing conditions and reused powder in the AM process by quantifying material evaporation.
This will allow to create printing strategies that mitigate the defect creation.
These results, combined with lab manufacturing, biological, degradation and microstructural characterization at IMDEA Materials will help to accelerate material development for additive manufacturing, qualify alloys for biomedical applications and optimize their powder recycling to ensure that the recycled powder meets the required standards for AM applications.
In this study, the candidate main task is to.
optimize printing parameters, design scaffold structures with functional gradients, characterize the printing process with advanced synchrotron techniques, characterize the material in the lab, implement new strategies to improve the material behavior Requirements The position is most appropriate for recent master's graduates (or soon to graduate) in fields related to material science and engineering, or related disciplines with excellent academic credentials.
Programming knowledge in any language, preferably Python for compatibility with already developed work will be valued.
Full proficiency in English, oral and written, is mandatory.
Interested candidates should submit their Curriculum Vitae, a brief cover letter addressing their motivation, as well as academic credentials.
