Double Extruder

The extruder in a 3D printer is responsible for accurately controlling and supplying the right amount of filament to the hot-end, where it melts and is then deposited in thin layers to build the desired object. When printing requires two different colors or materials, a Dual-Nozzle Extruder—also known as a Dual Extruder or Double Extruder—is used. This setup allows for seamless switching between filaments, enabling more complex and colorful prints with improved precision and efficiency.
