The dehydrated scaffold (denoted as dry weight) were soaked in water for a 24 h period and the dry weight was used to calculate the swelling ratio (%). This is provided for (a) ABS and (b) PVA cryogels, as well as (c) HIPS and (d) PVA hydrogels. The scaffolds fabricated in PVA molds had significantly different swelling ratios between the different shapes (p < 0.05), while the cryogels fabricated in ABS molds and the hydrogels fabricated in HIPS molds were similar between the different shapes.
