Description:

The 3D pen nozzle is essentially the "print head" of a 3D pen. It heats filament (usually PLA or ABS) and extrudes it in a controlled stream so you can draw freehand or repair 3D prints. Nozzles come in different sizes and shapes, influencing the thickness and style of extrusion. Because they operate at high temperatures, they are prone to clogs and wear, making replacement or cleaning essential for smooth operation.
