This project explores a continuous spiral approach to 3D printing, departing from traditional horizontal layering to produce a lightweight, open structure adaptable to non-linear surfaces. By manipulating parametric variables like the amplitude and frequency of undulations in the XY and Z planes, we control the form’s adaptability and visual complexity, allowing for intentional coil misalignments that enhance openness and shadow effects. These adjustments enable the structure to enclose irregular stones without requiring precise stacking, making it suitable for irregular, organic settings. Tested as an architectural pavilion, the design casts dynamic shadows and accommodates natural materials in a way that square or rigid forms cannot.
