We introduce DuoMorph, a design and fabrication method that synergistically integrates Fused Deposition Modeling(FDM) printing and pneumatic actuation to create novel shape-changing interfaces. In DuoMorph, the printed structures and heat-sealed pneumatic elements are mutually designed to actuate and constrain each other, enabling functions that are difficult for either component to achieve in isolation. Moreover, the entire hybrid structure can be fabricated through a single, seamless process using only a standard FDM printer—including both heat-sealing and 3D/4D printing. In this paper, we define a design space including four primitive categories that capture the fundamental ways in which printed and pneumatic components can interact. To support this process, we present a fabrication method and an accompanying design tool. Finally, we demonstrate the potential of DuoMorph through example applications and performance demonstrations.

In our everyday eating habits, we benefit from the diverse properties of natural food ingredients, from their taste and aroma to their texture. To further expand this potential, we draw inspiration from architected materials, in which engineered structures impart new mechanical properties. Building on this idea, we introduce kirigami and origami structures into fresh ingredients to embed new functionalities. Our design tool let users create custom, interchangeable rollers that apply cuts and folds to thinly sliced ingredients. By combining different structures with the inherent properties of food, users can transform everyday eating experiences across various contexts. To support users, we share experimental results with example ingredients to help them identify appropriate design parameters. Finally, we present several exemplar concepts in a recipe-style format to illustrate new interaction possibilities enabled by our reproducible fabrication pipeline.
