Highly porous scaffolds with an overall volume up to 30 cm 3 and porosities in the range from 80% to 93% were prepared from degradable poly(ether)esterurethane by thermally‐induced phase separation (TIPS) and subsequent solvent sublimation. The variation of the polymer concentration when applying a fixed TIPS cooling protocol led to an adjustment in pore size as well as in pore size distribution. While polymer concentrations of 5, 7.5 and 10 wt% resulted in averaged pore sizes ranging from 70 to 90 µm with a broad pore size distribution (according to µ‐CT analysis) for polymer concentrations of 15 wt% a significant lower averaged pore size of 50 µm with a narrow pore size distribution was obtained.
