| Abstract Scope |
4D additive manufacturing (4DAM) refers to the capability of parts to change shape in response to an external stimulus after 3D printing; that is, time is the 4th dimension. The shape memory effect or design residual stresses can cause such shape change. Of interest in this work is the application of AM to fabricate complex shaped devices and integral device architectures that enable significant device simplification and part count reduction. Key to taking advantage of 4DAM is the ability to systematically design devices that demonstrate desired shape changes while being manufacturable with existing materials. In this talk, I briefly survey the 4DAM field, present some state-of-the-art devices, and outline new approaches for systematic engineering design of 4DAM devices. A series of morphing and deployable device designs are demonstrated using both simple components and origami constructs. |
