Geometric Structures in Textile Design Made with 3D Printing

3D printing is a well-known technology for producing 3D objects by depositing successive layers of material. Among its many applications, the fashion industry has taken advantage of this technology to revolutionize its brands. Due to the unique properties of textiles, such as comfort, flexibility, etc., attempts have been made to create textile-like structures. Structures with different geometries were designed and printed using different materials ranging from rigid to flexible. In this study, three different basic geometric structures were designed using the Blender program (a free open-source 3D modelling software). Each geometric structure was designed in two different sizes with smaller and larger basic structural elements. In this case, six different models were created. The aim of this study was to compare the textile-like surfaces of different basic geometric shapes produced with 3D printers. It also aimed to investigate the use of surfaces designed with basic geometric shap...

This design-led research investigates the development of self-forming wearable composite structures by 3D printing semi-elastic embossed patterns out of semi-elastic Thermoplastic Polyurethane 95 (TPU95) filament on pre-stretched textiles and releasing the stress after the printing has been completed. In particular, the study presents and compares two methods of ‘file to fabrication’ techniques for generating self-forming textile shell structures: The first is based on printed patterns related to their stress line simulation and the second on modified geometrical patterns in relation to the curvature analysis of the objects. Furthermore, we investigate the buckling degree of the composites in relation to their fabric thickness and elasticity. The findings emphasise the advantages and challenges of each method as well as presenting a comparative table chart highlighting the relationship between material properties, pattern geometry and the formal vocabulary of the composite shells.
Investigation of Performance Characteristics of 3D Printing Textiles in Terms of Design and Material

New technologies that are used in the producing and processing of textile surfaces provide significant advantages for the designer. One of the important technologies that offer today's design advantage is three-dimensional "3D" printers. This study attempted to determine the effect of design features used on textile surfaces produced with different 3D printers and materials on performance characteristics. This researchaimed to examine and compare the performance characteristics of 3D printers, the relationships between 3D printers and the different materials required by these printers, and one-piece and multi-pieces designs. Accordingly, textile surfaces were produced with 3D printers and the performance properties of these surfaces were determined. Significant differences were observed in the performance of textiles based on the breaking, bursting and weight determination tests. These differences were discussed in terms of the design's structural characteristics, material and the ways of 3D printing to stacking material. Consequently, although the performances of 3D textiles get the better of one another, their breaking and bursting strengths are found to be lower than the conventional fabrics.

In this article, an experimental investigation was conducted to study the effects of 3D printed structured fabrics on the tensile strength of two additive manufacturing technologies: (i) fused deposition modeling (FDM); and (ii) stereolithography (SLA). Three types of structured fabrics were designed in a linked fabric structure, which resembled the main characteristics of a conventional textile. Through computer-aided design (CAD), the textile structures were sketched, which, in a STL format, were transferred to 3D printing software, and consequently, they were printed. The specimens were subjected to tensile tests to analyse the behaviour of the linked structures under tensile loads. The results obtained indicated that the elements structured in a linked fabric pattern showed a statistically significant effect between the design of the 3D printed structured fabric and its tensile strength. Some important properties in textiles, fabric areal density, fineness (tex) and fabric flexi...
3D Printing Technology in Textile and Fashion Industry

The extraordinary thing about the application of 3D printing technology is that it can be used to create accessible items customized to personal needs. In the fashion industry, there is a need for individualized protective equipment. The possibility of applying new technologies such as 3D modelling of protective elements that can be made by using 3D printers is presented in this paper. 3D modelling and additive technologies (3D printing) can be used in the development of protective work clothing. The fabrication process only requires the digital fi le with the 3D model and the right material - we chose to use thermoplastic polyurethane (TPU).The design samples were constructed and modelled using a software program called Rhinoceros. The samples can be integrated into the clothing item, in order to follow the body shape and to provide the necessary protection. Purpose. This paper aims to explore the applicability of 3D printing materials using thermoplastic polyurethane (TPU) for the...
Design and Development of 3D Printed High Performance Textile Structures for Composites
Volume!, 2017
Three dimensional (3D) printers offer a variety of design and geometry options, which are substantially demanded in textile industry. In this study, the aim is to produce neat nylon and glass fiber reinforced 3D printed honeycombs and introduce them into the structural composites to enhance the overall flexural and compressive properties. A significant increase in the mechanical response is observed, both in flexural and compression modes, when compared to sandwich composites with commercial aluminum honeycombs. In particular, the increase in compressive properties of 3D printed glass fiber reinforced nylon structures is attributed to the combined effect of the two factors as the inherent strength of glass fibers and well-designed filler geometry.
