Abstract Scope |
4D printing allows for otherwise static 3D printed structures to change form, modifying configuration or function with time in response to external stimuli such as temperature, light, electrical current, etc. A variety of geometries have been previously explored in the context of 4D printing including foldable surfaces (e.g. Origami), lattices and bio-inspired shapes; however, with advances in solid modeling software tools, more sophisticated spatially-varying lattices are now easily generated to further optimize the mechanical performance and functionality of a 4D printed structure. In this work, complex lattices are created to bend at specific locations with intentionally-reduced stiffness and improved compliance based on locally-reduced strut dimensions. By simulating and experimentally demonstrating more complex geometries in the study of 4D printing, new applications can be considered that were not possible previously with tailored performance allowing for balancing between weight and endurance. |
