Abstract :Additively manufactured Co-Cr lattice structures are promising choices especially in medical applications. This study involves the designing and fabrication of a novel lattice structures with FCCZZ insert ignore into journalissuearticles values(face-centered cubic with exterior and interior vertical struts); unit cell topology. The manufacturability by selective laser melting insert ignore into journalissuearticles values(SLM); and the load-bearing capacity of this structure were examined by utilizing scanning electron microscope insert ignore into journalissuearticles values(SEM); observations and uniaxial compression tests. The samples with FCCZ insert ignore into journalissuearticles values(face-centered cubic with vertical struts); structures were also produced and analyzed for comparison. The designed lattice structures were successfully manufactured by SLM even though an approximately 1.5-2% increase in the theoretical relative density values was observed. The novel FCCZZ samples exhibited superior performance in terms of the load-bearing capacity compared to FCCZ samples by possessing 17% higher specific strength value.
