In this study, morphological and mechanical characterization was performed on Ti6Al4V
scaffolds produced with a Rapid Prototyping (RP) technique called Selective Laser Melting (SLM).
Scaffolds with different pore sizes were designed and manufactured. Pore size measurements obtained by
light microscopic and (-CT imaging showed significant differences between designed and produced pore
size values, but no significant difference within scaffolds batches produced over time was found .
Compression tests, performed on cylindrical porous structures, resulted in a low inter batch variability
of the stiffness. This work showed that for SLM produced Ti6Al4V scaffolds the designed morphological
(pore and beam size) values differ from the produced values but that the process is consistent. Taking the
offset between designed pore value and real pore value in to account, it was concluded that SLM can
built structures with controlled pore and beam size dimensions with a minimal pore and beam size of 372
± 12µm and 190 ± 6µm respectively.
