A three-dimensionally (3D) printed acrylate polymer without filler, printed by stereolithography, has previously been shown to be inherently piezoelectric in the out-of-plane and in-plane directions in the absence of electrical poling. This work has shown that the longitudinal piezoelectric coupling coefficient d is increased by poling at an electric field of 2400 V m−1 by up to about 200%. The poling takes 60 min for either direction. The effect of in-plane poling on the in-plane piezoelectric…
