A filament, often referred to as thread, is a long, thin strand of material used in various applications, including sewing, weaving, and crafting. Filaments can be made from natural fibers like cotton or silk, or synthetic materials such as polyester and nylon. Their strength and flexibility make them ideal for creating durable fabrics and textiles. In addition to textiles, filaments are also used in other fields, such as 3D printing, where they serve as the raw material for creating objects. Different types of filaments, like PLA and ABS, have unique properties that cater to specific printing needs and applications.
