An investigation into development of porous medical implant scaffolds via laser additive manufacturing
The objective was to attempt to develop and evaluate the porous medical implant scaffolds designed via digital method and fabricated by laser additive manufacturing.A porous artificial femur model and several vessel scaffolds with customized design were created based upon the widely used Computed Tomography (CT) technology and Pro/Engineer software,and then were obtained by selective laser melting of powdered titanium-alloy material.The fabricating results showed that supports could be avoided with improvement of the processability of lattice,and porous scaffolds with good interconnectivity could be successfully fabricated.Some issues also arose,such as the low geometric accuracy of lattices.The exploited design freedom is an expected benefit in medical field because of the individual characteristic of each patient.It is expected that more scaffolds would be developed and be applied in practical fields with further study on design,process,and biocompatibility.
