ShrinCage: 4D Printing Accessories that Self-Adapt


3D printing technology makes Do-It-Yourself and reforming everyday objects a reality. However, designing and fabricating attachments that can seamlessly adapt existing objects to extended functionality is a laborious process, which requires accurate measuring, modeling, manufacturing, and assembly. This paper presents ShrinCage, a 4D printing system that allows novices to easily create shrinkable adaptations to fit and fasten existing objects. Specifically, the design tool presented in this work aid in the design of attachment that adapts to irregular morphologies, which accommodates the variations in measurements and fabrication, subsequently simplifying the modeling and assembly processes. We further conduct mechanical tests and user studies to evaluate the availability and feasibility of this method. Numerous application examples created by ShrinCage prove that it can be adopted by aesthetic modification, assistive technology, repair, upcycling, and augmented 3D printing.
