About the Project

Project description:  

A porous implant can mimic natural bone more reliably and satisfies the biomechanics requirement. The main objective of this research will be to replace the solid titanium biomedical implant with a porous structure for enhanced performance and biocompatible characteristics. The research involves theoretical study, FEA computations, topology optimization (TO), additive manufacturing (AM), material characterization, and mechanical testing. TO algorithms will be employed to explore porous configurations with improved weight-to-stiffness ratios. The study will undertake the requirements of international standards for biomedical implants. Mechanical testing and material characterization of AM porous titanium implant will provide a good benchmark for evaluating the microstructure, tribological parameters, thermo-mechanical characteristics, and biocompatible characteristics. 

 Project objectives: 

  1. To provide a unique insight into topologically optimized porous titanium implant studies. 
  2. To provide a comprehensive step-by-step design and development approach for porous implants, its compliance with international standards, and unique benefits to the biomedical community. 
  3. To add a new value into the biomechanics and optimal parameters of porous implants, such as porosity, pore size and interconnectivity with favourable anisotropic topologies. 

Candidate Attributes:

We are looking for an inspiring candidate having a critical awareness of current problems, and new insights in fields relevant to this research project. The candidate must hold an engineering degree with a 2.1 grade (or above), or a post-graduate degree, in Mechanical, Manufacturing, or Biomedical Engineering. The nature of the project demands that the candidate should have an ability to demonstrate a systematic understanding of knowledge at the forefront of a relevant field of learning: e.g., numerical modelling (finite element based), biomaterials, additive manufacturing, and materials characterisation techniques.
