Statement

Bio-inspired 3D Printed Hygroscopic Prog. Material Systems Biological systems address performance challenges with limited resources by using complex and multi-layer structured assemblies. Unlike conventional engineering systems, biological systems rely on differentiated materials and structured material systems that are at the same time sensor, actuator, and regulator.The piece utilizes the dimensional change of hygroscopic 3DP elements to trigger a shape change in response to fluctuations of external relative humidity. Computational tools are used to design the complex interaction between the various programmable and functional parameters of the material structure, making it feasible to manage complex four-dimensional articulations

Artworks

Inspired by Nature and Pine Scale Structures, the presented work uses 3D printing processes to build functionally differentiated material systems that are highly in-tune with changing weather conditions. FFF and computational tools allow for direct control of material composition and variation through bespoke NC additive processes. Through computational tools and material research, it is possible to design anisotropic material structures for stimulus responsive kinematic actuation. In other words, customized 3DP apertures that can transform with changing weather patterns.
