Fig. 1: Polymer-substrate electrification.
From: Direct observation of electrostatic charging in 3D printing
a Illustration of polymer electrification mechanisms observed during 3D printing. b Electrostatic mapping of five polymers (ABS, PETG, PLA, TPU, and Nylon) on three different substrates: glass, steel, and PTFE. c Average potential of pixels in each electrostatic mapping. d Triboelectric series depicting the electrification tendencies of five polymers on three different substrates. e Dissipation of the most electrified region of the samples for each substrate. All electrostatic maps are sized at 30 mm × 30 mm and only one layer with a thickness of 0.2 mm. Objects were printed with the substrates under room-temperature. Error bars represent the standard deviation of the electrostatic potential values, averaged over at least three independent experiments per condition.
