PixBric: Precision Morphological Control of Pre-Stretched Fabrics Through Tessellated Primitive Geometries

3D printing patterns onto pre-stretched fabrics has emerged as a promising method for the rapid fabrication of self-shaping textiles.However, the influence of design parameters on morphing behavior remains insufficiently explored, often resulting in heuristicdriven decisions.This study introduces PixBric, a pixel-based textile methodology composed of primitive geometries designed to induce controlled morphing behaviors-such as undulation and bending-and mechanical properties including multistability.By parametrically adjusting geometry, thickness, and inter-pixel spacing, PixBric enables precise morphing outcomes.The framework includes a morphing simulation tool and a design chart linking geometric variables to deformation results.We also propose a streamlined fabrication protocol using biaxial pre-stretching with magnetic framing.These contributions establish a systematic design approach for the functional and interactive deployment of selfshaping textile structures.
