3D printing of shape memory poly(d,l‐lactide‐co‐trimethylene carbonate) by direct ink writing for shape‐changing structures

Four‐dimensional (4D) printing of shape memory materials has attracted increasing interests for personalized structures. In this study, a biocompatible poly( d , l ‐lactide‐ co ‐trimethylene carbonate) (PLMC) is utilized to fabricate 4D shape‐changing structures with customized geometries through direct ink writing. The printed objects show shape transformations at different dimensions under thermal programming. The influence of the printing...
