ABSTRACT -

Latest SMP (Shape Memory Polymers) materials may allow to produce future building elements that change their shape in various ways. This study focuses on (1) developing shape-changing multi-materials from SMP and (2) control the change in shape by harnessing its thermal responsiveness. We focus on the manufacturing of SMP/PLA (Polylactic acid), SMP/TPU (Thermoplastic Polyurethane) and SMP/PETG (Polyethylene terephthalate glycol) composites, with special attention to SMP/TPU and SMP/PETG composites and their material behaviors compared to single SMPs. The first step was to initially investigate shape-changing and self-transforming composites. We report on (a) a thermo-active SMP capable of recovering from a shape-change after exposure to a temperature of 55°C and (b) testing the concept of 4D printing with FFF (Fused Filament Fabrication) technique. Their printability and cohesion were tested, and consequently, a geometric connection strategy was introduced to design SMP/PLA and SMP/PETG composites. Finally, we managed to activate shape-change in an SMP/PETG with embedded heating wires controlled by a microcontroller.
