Design and Simulation of a Titanium Alloy Lattice Bone Plate for 3D Printing

In order to improve the stress shielding effect caused by excessive elastic modulus of metal plates during fracture healing, a kind of 3D printing oriented lattice structure plate is designed based on topology optimization and the finite element modeling technology. A simplified finite element model...
