Evaluations of Co-Cr-Mo meta-biomaterial manufactured by selective laser melting for orthopaedic application

Meta-biomaterial with rationally design geometrical features provides an exciting opportunity to reduce stress shielding effect and enhance biological fixation as vital criteria for longer durability load-bearing implants. Recently, selective laser melting (SLM), an additive manufacturing has shown...
