초록

(Background and Purpose) This research paper aims to investigate a unique design process that digitally manipulates the morphological transformations of a heat-induced self-reinforcing polymer. The principle of the heat-induced contractile polymer has long been implemented in various industries such as packaging and fashion. While other industries have embraced the full potential of the particular soft material, it is still a relatively new material to be further explored in the field of architecture. Yet, with the application of computational tools to architectural form-making and fabrication methodologies, morphological and structural behaviors of heat-induced polymer could become an active material for architectural projects. (Method) There are two modes distinguished in the presented research methodology. First of all, the author conducts the physical investigation of the material system of heat-induced polymers as a design driver. In this stage, the author computes the material behavior of the polymer sheet considering the material thickness of the polymer sheet and the traits of contractile deformation based on the time of heat exposure and the level of temperature on the material. Second, the author explores the digital investigation of a transition system of the physical properties to digital simulation then from the digital model to a fabricatable artifact based on the physical investigation of the heat-induced polymer sheet. In this stage, A series of computational strategies are applied to evaluate and analyze the design that eventually led to the making process. Finally, the latter part of this research paper showcases a built case study titled De:flatable. The study demonstrates the process of digitally comprehending the morphological transformation of a soft material, ultimately realizing the most optimal form through rapid prototyping with varying parameters. (Results) The presented paper proves the resilience of the design process and aims to revisit the reciprocity of physical and digital, of formal and structural, and of design and fabrication through comparing the physical scale models and digital form-finding prototypes. And in lieu of the spirit of recalibration, the research is experimentation in imprecision. (Conclusions) Not only an imprecision by the nature of the polymer’s intrinsic soft materiality but the imprecision of the digital translation of the morphological behavior of viscoelasticity. But as the following research demonstrates, it is within the imprecision and the infidelity of both physical material and computation tools that interpret the material that leads to the production of a form and a design process that hints at new possibilities in architectural design.
