ABSTRACT
In traumatological cases requiring permanent implantation, the high stiffness of concise metal bone plates can lead to an undesirable stress shielding effect. This research presents an implant design approach that reduces plate stiffness through the application of porous structures, thereby promoting bone tissue ingrowth. In the first step, the parameters of the lattice structure were optimized using finite element bending simulations. The resulting specimens were manufactured from Ti-6Al-4V alloy using direct metal laser sintering (DMLS) technology on an EOS M290 metal 3D printer. Subsequently, the specimens were subjected to cyclic fatigue testing. The results are promising, although further optimization and research are required.
