Fig. 4From: Printing tissue-engineered scaffolds made of polycaprolactone and nano-hydroxyapatite with mechanical properties appropriate for trabecular bone substitutesRepresentative SEM images of scaffolds with their schematic illustrations: A lattice side, B staggered side. The gap between the strands refers to the pore size associated with each scaffold. L refers to the distance between strands and d refers to strand diameterBack to article page
