Despite the minimal differences in Tg, processability was affected rather markedly. The printability of A-BuOzi-A showed a similar result to A-PentOx-A (Supporting Information Figure ). Starting from 155 °C, fiber extrusion was achieved, however, for both plasticizers poor fiber attachment to the collector plate was observed, resulting in overall bad print quality. By increasing the temperature to 160 °C, the fibers stuck on the collector plate and box-like structures with reasonably good fiber stacking can be observed, with improved fiber stacking for the samples containing ethylene glycol. Further increasing the temperature to 165 °C resulted in better fiber stacking for triethyl citrate. A different behavior was observed for A-BuOx-A and the plasticizers (Supporting Information Figure ). Here, phase separation between the polymer and triethyl citrate was observed, preventing fiber extrusion during the print process (Supporting Information Figure ). In contrast, the addition of ethylene glycol led to a printable blend from 160 °C and a further temperature increase to 165 and 170 °C resulted in improved fiber stacking. Even though the viscosity of A-BuOx-A was found comparable to A-PentOx-A, clear differences in printability were observed. Testing the printability of A-PentOzi-A with the plasticizers, resulted in polymer extrusion from 160 °C, but poor fiber attachment to the collector plate (Supporting Information Figure ). Increasing the print temperature to 170 °C resolved the problem.
