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
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.
