Kinetic Architecture with 3DP & Shape Memory Alloys
MAS Thesis Research - Rigidity, Flexibility, and Actuation • ETH Zurich
@ETH Zurich - Digital Building Technologies

This research develops an experimental program with a series of tests, enabling higher controllability of shape morphing behavior through complex geometric features and investigating possible approaches to the material- and energy-efficient actuation. For material-efficient shape-morphing, a minimum amount of SMA-wire is embedded as a muscle into flexible and motion-optimized 3D print.
**Key Technologies:** - Kinetic architecture - Multi-material 3D printing - Shape memory alloy - Flexible materials - Geometrical grading
**Tools used:** - Raise 3d Pro 2 - Prusa i3 MK3 - Markforged Onyx One - Cinema 4D simulations - Grasshopper - Ultimaker Cura Slicer - Realflow Fluid Simulations - Ideamaker 3d
**Outcomes and Real-world scenarios**
The result of the thesis provides the analysis of the tests that focus on the range of motion, repeatability, and material and energy efficiency. Further, prototyping a lighting installation, and a facade element tries to address the upscaling process. The findings are then consolidated with scenario building in contemporary architectural context.
This thesis contributes to the feasibility study of using novel composites from innovative materials under innovative processes to open the discussion towards its real-world applications.
