Compared to the previously published study on the fabrication of IND loaded microfibers fabricated via MEW with a POx/POzi based polymer system, we were not able to lower the fabrication temperature significantly (135 °C in the previous study for 50 wt% IND loading). However, we were able to prepare a polymer-drug-plasticizer system, which does not require additional hot melt extrusion to obtain sufficient mixing of the components and even after several hours at the printing temperature, no indicators of drug degradation, either visibly (indicated by discoloration) or by H NMR spectra of the printed scaffolds were observed (Supporting Information Figure ).
