Development of bone bioimplants with various porous microstructures and lattices with FRep
Modeling hemo-mandible bone implant with various porous structures with the help of FRep approach and C++-based FRepCAM software. The goal is to reveal the optimal microstructure for 3D printing of such a bioimplant, print it, and provide porosity and compression tests. Example of the model with regular lattice was printed by photopolymer on Zortrax Inkspire 3D printer at Additive Technologies Laboratory at Skoltech.
