A metal dual-gear extruder is a type of extruder mechanism used in 3D printing. It consists of two interlocking gears made of metal that are designed to grip and push a filament through a hot end to melt and deposit it onto a printing surface.
The dual-gear design provides more reliable and precise control over the filament, allowing for smoother and more consistent extrusion. The metal construction also makes the extruder more durable and resistant to wear and tear, especially when compared to extruders made from plastic.
Metal dual-gear extruders are commonly used in higher-end 3D printers and are popular with enthusiasts and professionals who require high-quality and reliable 3D prints.
