a Electrostatic mappings depicting the influence of layer count (one to four layers) for the five polymers. b Comparison of four layers of ABS, printed at room temperature and under the standard substrate temperature. c Representative diagonal line profiles extracted from the mappings shown in (b). d Charge build-up and decay experiments showcasing 2 layers of PLA printed on top of 2 previously printed layers. All electrostatic maps are sized at 40 mm x 40 mm and each layer is 0.2 mm thick.
