Development of textile structures using 3D prototyping technologies

The object of the research is pseudotextile mesh structures with three-dimensional hinged joints, manufactured by 3D prototyping methods. One of the main tasks in the field of 3D printing of textile materials is to ensure their flexibility, elasticity and adaptability to the shape of the human body. Materials produced by traditional 3D printing methods have high rigidity, which limits their application in the light industry. During the study, a concept for creating pseudotextile materials based on flexible network structures using spherical three-dimensional hinges was developed. The proposed structure allows for achieve the necessary flexibility and deformation capabilities characteristic of traditional textile materials. Modeling and experimental samples demonstrated that structures with three-layer hinged joints provide spatial variability of shape, while the use of eccentricity in the hinges allows to adjust the rigidity of the structures. The obtained results can be attributed to the use of three-level spherical hinge joints, which provide spatial mobility of individual elements of the structure, as well as numerical modeling to optimize the sizes of structural elements. The implemented models confirm that the mechanical properties of the synthesized structures can be controlled by changing their geometry. The developed structures can be utilized in the clothing production where high flexibility of the material is required, as well as in the creation of adaptive textile products for medical purposes, in particular for compression therapy or automated massage. Additionally, such materials can be used in the decorative design of fashion products.
