For the samples containing additional plasticizer, scaffolds still showed poor print quality due to poor fiber stacking at a print temperature of 125 °C, but increasing the temperature to 130 °C or 135 °C improved the fiber stacking. For all the tested samples, it appeared, that a melt viscosity of approximately 100 Pa*s resulted in the best printing quality in terms of fiber stacking. Importantly, the addition of the plasticizer did not markedly reduced the print temperature, but ensured a better stacking of the deposited microfibers. Apart from fiber stacking, the applicable collector speed depended on whether the plasticizer was added or not. However, as discussed before, the print parameters had to be adjusted for each sample separately. In general, adding triethyl citrate and increasing the print temperature allowed for an increased translation speed for all drug loaded samples (Table ). The only exception was A-PentOzi-A, for which the applied translation speed was constant at 360 mm*min -1 for all tested temperatures without plasticizer. By adding the plasticizer, the speed could be increased to 480 mm*min -1 at 135 °C.
