Singapore researchers evaluate durability of 4D printed parts
Researchers from Singapore have investigated the durability of 4D printed structures. 4D printing, opposed to 3D, is a term that relates to objects that can adapt over time once they have been 3D printed. The structures rely on shape memory polymers which are able to transform into a certain shape.
3D Printing Industry has reported on the potential of 4D printed structures recently with a separate study also from Singapore. In this case, researchers showcased the simplicity of fabrication and the application of 4D printed objects.
However, in a new study stemming from Nanyang Technological University, researchers evaluate the performance of these structures since, as they explain, “high shape fixity, shape recovery, and prolonged shape memory cycle life are desirable aspects of 4D printed parts; however, the durability of 4D printed parts is rarely investigated.”
