a Oscillatory temperature sweep of dry DTPUs with different MPEG and PEG/PCL-triol showing transition temperature between elastic state and viscoelastic liquid state. b Viscosity of DTPU-0.5-2k, DTPU-0.25-4k, and DTPU-0.5-4k as a function of temperature. c Oscillatory alternating temperature sweep of DTPU-0.25-4k. d Printing paths and as-prepared structures printed using DTPU-0.25-4k. Tensile strength e, Young’s modulus f, and tensile strain at break g, of dry scaffolds constructed with different molding methods. h Swelling ratio of scaffolds constructed with different molding methods. Values in (e–h) represent mean ± SD. One-way analysis of variance (ANOVA), Tukey’s post hoc test. (n = 3).
