LPBF/binder jetting technique will be used to produce porous structures inside the produced implants with a desired porosity level (~30%). An outermost dense structure will also be fabricated using different LPBF settings to emulate human bone structures. Since LPBF-built surfaces typically possess higher surface roughness (~10-20 μm), laser post-processing techniques (LST, LP) will be subsequently employed to achieve sub-micron surface roughness (<0.5 μm) on the outermost layers of the implants. It is further envisaged that the surface cracks, defects would be eliminated by employing LP which would ultimately improve the parts’ surface integrity.

The student will be working within the High-Value Manufacturing Group’s two major research labs - Additive Manufacturing and Micro and Nano-manufacturing.
