Mechanical behavior and failure mode of body-centered cubic, gyroid, diamond, and Voronoi functionally graded additively manufactured biomedical lattice structures.

Given the capability to produce parts with complex geometries, powder bed fusion using a laser beam (PBF-LB), one of several additive manufacturing techniques, is becoming increasingly prevalent in both research and industry. Advances in the development of biomedical lattice structures show a trend in the use of functional gradients for greater customization and adjustment of mechanical properties according to the demands. This study analyzed four biomedical potential lattice structures (regular and graded) manufactured using PBF-LB in Ti6Al4V alloy.
