Active Printed Materials for Complex Self-Evolving Deformations

We propose a new design of complex self-evolving structures that vary over time due to environmental interaction. In conventional 3D printing systems, materials are meant to be stable rather than active and fabricated models are designed and printed as static objects. Here, we introduce a novel approach for simulating and fabricating self-evolving structures that transform into a predetermined shape, changing property and function after fabrication. The new locally coordinated bending primitives combine into a single system, allowing for a global deformation which can stretch, fold and bend given environmental stimulus

In this research, the material assembly, which is defined as a material whose properties derive from the programming of raw matter to form unique internal structures, manifests through the technique of knitting, a material practice defined by pattern as rule-based code. A key contribution of this research is the development of a framework to help designers better understand how the topology of a knit structure can align with formal and structural motivations of tension activated architectural forms. This was accomplished through the identification of the knit pattern as code. Whereas traditionally the pattern is a static visual representation, in this research it is both the physical sequence of stitches and the dynamic properties of each stitch within a digital model. The dynamic properties of the physical material communicate through the knit pattern to the digital model, which explores the possibilities of form within the constraints of the material to remap the pattern's code and thereby re-informing the physical. This new framework may help designers create and evaluate material assemblies to better satisfy the local and global needs of form, structure, and aesthetics. The play between the physical and the digital is recursive, experimental, and interpretative - each informs the other while never truly resulting in the same output.by Carrie Lee McKnelly.S.M
