The shift towards sustainability in the fashion industry has become an urgent necessity and a national duty, where the life cycle of garments poses a negative impact on the environment, which increases strongly with the huge increase in the daily consumption of garments and fast fashion. One of the most prominent solutions that have been proposed is to change the manufacturing system in a way that would help reduce costs, reduce supply and provide products that are more closely related to the individual customer need. Accessories such as (closers) are an important part of the fashion industry, and therefore, this study aimed to produce closers using (FDM) technology, which is one of the least expensive and most widespread 3D printing technologies. These closers are then tested in the laboratory according to AATCC standard specifications for garments and closers to ensure the applicability of this technology in the implementation of closers for designers and manufacturers in medium and small facilities. This study relied on the experimental exploratory approach, and the results proved the success of the proposed closers, as the implemented models passed the standard tests with distinction.
