Abstract
The open cell structure is commonly used in the medical device industry and consists of small struts connected to each other. Relatively new additive manufacturing technique “SLS” has been used in this study. This approach allows to create a sufficiently small specimens to represent each strut in a commercially available orthopaedic porous structure. Pure titanium Grade 2 (CP-Ti grade 2) powder has been used during the experiments because of higher resistance to corrosion and it is one of the most biocompatible metal. The mechanical response of each strut affects the general behaviour of the porous system which influences stress shielding and bone attachment. In this study, small strut size effect and building direction of mechanical response have been investigated in order to provide vital data for upcoming rhombic dodecahedron structure FEM research
