A filament refers to a slender thread or fiber, often used in the context of materials such as textiles or 3D printing. In the realm of lighting, a filament pertains to a wire, typically tungsten, inside an incandescent light bulb that emits light when heated by an electric current. In the field of biology, a filament can describe a long, thin structure, such as the stalk of a stamen in a flower. In 3D printing technology, a filament is a material (usually thermoplastic) fed into a 3D printer to create printed objects layer by layer. The term finds diverse applications across various disciplines, embodying a common theme of slender, elongated structures or materials.
