Reversible deformation structure fabricated by 4D printing can be applied in various fields, such as actuators, intelligent mechanisms, and soft robots. In this study, 4D filaments for use in fused deposition modeling (FDM) 3D printers were fabricated by melt extrusion process mixing polylactic acid...
