Additive manufactured Ti-6Al-4V lattice structures for use in orthopedic implants

Presenter(s)

Description

The call for orthopedic implants is a growing concern with an ever-rising aging population. Current orthopedic implants provide good mechanical strength and stability, with some offering surface area bone growth. Lattice structures manufactured via laser powder bed fusion offer patient specific orthopedic implants with mechanical properties similar to bone, less weight and promotion of internal bone growth for better fixation. Two different lattice structures of cubic and diamond were printed in Ti-6Al-4V via an open architecture selective laser melting machine. These lattice structures have varied pore sizes of 400, 500, 600 and 900µm. Compression and tensile testing were performed to identify mechanical properties.. Properties needed to promote osseointegration are reviewed, such as pore size and geometry .
