Interaction of cell culture with composition effects on the mechanical properties of polycaprolactone-hydroxyapatite scaffolds fabricated via selective laser sintering (SLS)

► PCL-HA (0, 15, 30 wt.%) scaffolds were manufactured by selective laser sintering. ► Mechanical properties are examined as indicators of cell integration. ► Alamar blue tests verified that mechanical properties are good indicators for the degree of cell attachment. ► μ-CT showed that cells were evenly distributed within the micro-porosity of the struts. ► Lower HA content (15 wt.%) showed better initial metabolic activity, however by day 14 the performance was equal.
