4D Printing on Textiles: developing a file to fabrication framework for self-forming, composite wearables

This research is investigating the development of self-forming wearable composite structures by 3D printing semi-elastic embossed patterns out of semi-elastic Thermoplastic Polyurethane 95 filament on pre-stretched textiles and releasing the stress after the printing has been completed. In particular, we will present and compare two methods of ‘file to fabrication’ techniques for generating self-forming textile shell structures: one based on printed patterns related to their stress line simulation and a second based on modified geometrical patterns in relation to their curvature analysis. Furthermore, we will investigate the buckling degree of the composites in relation to their fabric thickness and elasticity. Our findings will emphasize the advantages and challenges of each method as well as present a comparative table chart highlighting the relationship between material properties, pattern geometry and the formal vocabulary of the composite shells
