Direct observation of electrostatic charging in 3D printing.

ABSTRACT: The spontaneous electrification of surfaces and interfaces is a widespread phenomenon that produces unexpected effects in chemical reactivity and mass charge transfer, revealed in abundant literature over the past twenty years. The pervasive presence of electrostatic charges originates from many sources, including friction, mechanochemical reactions, phase change, flexoelectricity, and others. Since fused deposition modeling undergoes most well-known electrification mechanisms, it would be not surprising that 3D-printed objects display large amounts of charge. Here we uncover the hitherto unexplored realm of electrostatic charging in 3D printing, underscores the impact of printing parameters on charge generation in polymers. Substrates, printing speed, temperature, and printing direction e
