Piezoelectric behavior of three-dimensionally printed acrylate polymer without filler or poling

We report the piezoelectric behavior of three-dimensionally layer-by-layer printed (bottom-up stereolithography, 21–46-µm layer thickness) polymer without filler or poling, using unmodified

Decreasing the shear stress-induced in-plane molecular alignment by unprecedented stereolithographic delay in three-dimensional printing

AbstractThe shear stress-induced in-plane molecular alignment in 3D printed polymer is decreased with an increased stereolithographic delay. The molecular alignment represented by the

Enhancing the inherent piezoelectric behavior of a three-dimensionally printed acrylate polymer by electrical poling

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
