Abstract

In the field of four-dimensional (4D) printing deformation, shape memory deformation can be achieved by changing printing parameters or materials. However, the effect of different thickness ratios between heterogeneous layers of the bilayer structure on deformation in 4D printing is still an unknown factor. A method for programming the fiber arrangement direction and the thickness ratio of the polylactic acid (PLA) layer and thermoplastic polyurethane (TPU) layer was proposed to achieve temperature-driven controllable deformation of the heterogeneous laminated bilayer structure. Three-dimensional (3D) printing method based on fused deposition modeling (FDM) technology was used to print homogeneous laminated structures, material distribution structures, and heterogeneous laminated bilayer structures, respectively. The thermal strain of homogeneous laminated structures with different fiber arrangement direction of PLA and TPU materials was analyzed. The effect of four printed material distribution structures on bending angle and bending response time of temperature-driven deformation in 4D printing was analyzed. The deformation performance of heterogeneous laminated bilayer structures with different thickness ratios between PLA layer and TPU layer were studied through a combination of theoretical analysis and experimental verification. The experimental results show that the bending curvature of the bilayer structure with the thickness ratio of 7:5 (PLA: TPU) is the maximum that is 1.11 cm−1. Four cross-shaped components were designed to demonstrate the programmability of heterogeneous laminated bilayer structure in 4D printing, and the controllable deformation of the programmable bilayer structure was verified through the printed rosette structure. Therefore, programming the fiber arrangement direction and the thickness ratio of the heterogeneous bilayer structure is an effective strategy for achieving temperature-driven controllable deformation in 4D printing.
