Project summary

The aim of the project is to explore the application possibilities of novel technologies, polymers, and polymer composite materials for use in implants with which the listed goals can be achieved. The main key issues and objectives are: Our research is based on two main parts. The first pillar is to improve the lubrication condition of metal–polymer sliding pairs. A comprehensive study of the effects that can be achieved by modifying the polymer material of the artificial joint by crosslinking by irradiation, surface modification by grafting, and by the creation of surface nano- and microstructures. We aim to investigate the effect of titanium-side modifications by creating volumetric structures. We also aim to map the obtained tribological and mechanical characteristics and explore the interactions between them. The second pillar is to develop a new implant manufacturing technology for the processing of medical-grade polymers to create customizable, economically manufacturable implants from polymers and polymer composites. We aim to explore the potential of FDM 3D printing, determine the effects of manufacturing technology parameters (filling structure, orientation, porosity) on tribological properties. We also aim to create direct, in situ surface microstructures to improve the wear properties of 3D printed structures, mapping their effect on the tribological behavior and compare the results with the reference UHMWPE samples. The results of the project will facilitate the creation of longer-lasting implants that withstand higher loads, customizable implants, and even additional patents that could be useful for the industry.
