Abstract
This work aims to characterize the mechanical behavior in uniaxial compression of two titanium alloy (Ti- 6Al-4V) cellular structures, with three different cell sizes each one, fabricated by the Electron Beam Melting® (EBM®) additive manufacturing process. Such structures have the potential to be applied in manufacturing stages of metal orthopedic implants with elastic modulus similar to the human bone, reducing the stress-shielding effect and improving osseointegration. Compression tests were carried out in order to find the correlation between mechanical properties and cell geometry. Results showed that for similar porosity, the compressive strength increase with the decrease of cell ligament length.
