Programmable 4D-Printed Responsive Structures

Article Preview

Abstract:

4D-printing has been emerged and developed from 3D-printing. The 4D-printing technology creates sophisticated structures in which can change over time to perform programmed functions. In this research, simply programmable 4D-printed responsive structures were designed, prepared and studied. The designed structures are influentially inspired by creatures and the customized 3D-printer was used. Magnetic crosslinked PVA was prepared and used as programmable 4D-printed responsive samples. Effect of PVA concentration on gel fraction was elucidated for the prepared crosslinked PVA. Fe3O4 particles were incorporated to the crosslinked polymer before manufacturing. Effect of speed of platform and effect of rate of syringe pump on the 4D-printed magnetic crosslinked PVA structure were investigated. Furthermore, the responsive property of the magnetic crosslinked PVA was determined.
