Glossary of 3D Printing Terms [1]

Extruder The extruder is one of the most critical components of a 3D printer. It is responsible for controlling the flow of filament material into the hot end of the printer, where it is melted and deposited layer by layer to form a 3D object. The extruder consists of two main sections: the cold end and the hot end. The cold end is responsible for gripping and feeding the filament into the hot end using a motorized mechanism, often a gear or direct drive system. The hot end heats the filament to its melting point, allowing it to be extruded through a nozzle onto the build platform. The extruder plays a key role in determining the quality of the printed object by regulating the flow and consistency of the filament. Advanced extruders may also include features like filament sensors, multi-material capabilities, or fine-tuned temperature control for printing various materials.
