Filament, an often overlooked but vital technological component, plays a significant role in our daily lives. When we think about electricity, lightbulbs inevitably come to mind. At the heart of every incandescent lightbulb is a filament. This thin wire, typically made of tungsten, heats up due to electrical resistance and emits light as a result. Beyond lightbulbs, filaments are used in 3D printing, providing a tangible form to digital designs. As technology evolves, these unsung heroes of innovation keep finding new applications, subtly but significantly impacting our lives.#16#
