A custom-built MEW printer similar to a previously described machine was used to process the polymer plasticizer-blends, polymer-drug blends and polymer-plasticizer-drug blends. The 3 mL glass syringes (Poulten & Graf GmbH, Wertheim, Germany) were loaded with different materials and heated for a minimum of 30 minutes prior to printing until the bubbles within the melt dissipated. For all experiments, a nozzle tip with an inner diameter of 0.65 mm (23G) was used and manually grinded to a length of 13 mm. Other applied printing parameters are listed in Table and Table .
