Abstract

Purpose

The purpose of this research is to design 3D print and analyze mechanical as well as microstructural behavior of interlaced fibrous structures using Dremel 3D45 additive manufacturing (AM) machine.

Design/methodology/approach

A series of plain and twill weave fabrics are designed using computer-aided design software Solidworks and printed using fused deposition modeling machines to determine the best model that could be printable. The structures were designed in such a way that the fabricated yarns with pure (PLA) were not sticking to each other in the fabric structure. The specimens were printed in vertical orientation and then tensile and three-point bending (flexural) tests were conducted for twill weave fabrics.

Findings

The tests showed that the mechanical strength was higher in the warp direction than in the weft direction. This difference was because of printing of continuous filament-like yarns in the warp direction and staple-like yarns in the weft direction. This orthotropic property of the material was verified by analyzing its microscopic structures via optical microscope.

Research limitations/implications

Future work should include improvement of the structure and exploration of different polymers and their composites to increase the tensile, bending and other strengths to make the 3D-printed structures more flexible and stronger. Future research should also focus on the large-scale manufacturing of 3D printed fabrics.

Practical implications

This paper supports work on wearable 3D-printed fabrics. The 3D-printed fabric will also contribute to new applications and products such as liquid filters.

Originality/value

The research done in this work is new and original. This paper contributes to new knowledge by providing a better understanding of polymers and their 3D printing capabilities to form a complex fabric structure.

Abstract

Purpose

Optimization of FDM process parameters has emerged as a major step toward mitigating the issue of reduced mechanical strength of fused deposition modeling (FDM) products. This study aims to evaluate the impact of process parameters on the mechanical properties of 3D-printed fabric yarns of three different materials, namely, polyethylene terephthalate glycol (PETG), nylon and thermoplastic polyurethane (TPU).

Design/methodology/approach

2/1 Twill fabric samples with variations of extrusion temperatures and printing profiles are produced, and the individual yarns, manually separated from the fabric samples, are tested for tensile strength, modulus, strain and energy at maximum force. The tensile test results are further subjected to statistical analysis with MINITAB software to detect the standard level of influence of each parameter and evaluate their significance.

Findings

Both extrusion temperature and printing profile, along with their interaction, are significantly important parameters for the mechanical behavior of PETG. However, for nylon and TPU, the influence of a few parameters is found to be insignificant. For all variations of fabric yarns, relatively lower extrusion temperature is concluded to be preferable for better mechanical properties.

Originality/value

This research is new and original. It provides knowledge about how FDM process parameters influence the mechanical behavior of fabrics. It also identifies the optimum process parameters for the best performance of the final product. This article can be a foundation for further parametric analysis of 3D-printed fabric. No artificial intelligence or similar software was used in the preparation of this manuscript.

Abstract

Investigated the effects of ISO 9000 standards on the US textile industry through an industry survey. Examined the relationship between product quality and ISO standards. Provides results on the effects of ISO 9000 on the textile industry, especially on product quality. Implementation of ISO helps to improve product and process quality, reduces rework and defective supplies, and can be used as a marketing tool. The cost of ISO 9000 certification was negligible compared to the benefits it provides. ISO certified companies reported that their total costs went down with regard to maintaining quality. With the implementation of ISO, management becomes committed to quality. ISO certified companies seem to have focused more clearly on quality of products and operations. ISO certification motivates employees to improve quality.
