Effect of Dexamethasone on Room Temperature Three-Dimensional Printing, Rheology, and Degradation of a Low Modulus Polyester for Soft Tissue Engineering

ACS Biomaterials Science & Engineering 2019 Volume 5, Issue 2, Pages 846–858

Three-dimensional (3D) printing has enabled benchtop fabrication of customized bioengineered constructs with intricate architectures. Various approaches are being explored to enable optimum integration of such constructs into the physiological environment including addition of bioactive fillers. In this work, we incorporated a corticosteroid drug, dexamethasone (Dex), in a low modulus polyester (SC5050) and examined the effect of Dex incorporation on solvent-, initiator-, and monomer-free pneumatic extrusion-based 3D printing of the polymer. Dex–SC5050 interactions were characterized by plotting thermodynamic binary phase diagrams based on the Flory–Huggins theory. The effect of Dex composition on the 3D printability of the SC5050 polyester was examined…
