In the samples without the plasticizer, the fiber attachment to the collector plate in the first layers was poor, resulting in an overall reduced print quality. At 125 °C the solidification of the polymer melt was too fast to get a proper attachment of the first drop of polymer melt on the collector plate from where the continuous fiber can be formed. Additionally, it was observed, that printing at 120 °C and 125 °C resulted in scaffolds with poor interlayer adhesion, presumably due to the rapid melt solidification. To overcome this issue, printing tests for the samples without added plasticizer were performed at 130 °C and 135 °C, resulting in better attachment of the first layer on the collector plate. However, the overall fiber stacking remained poor, potentially caused by electrostatic repulsion of the fibers due to ionizable IND.
