DLC Hardened Steel Nozzle 



This Hardened Steel Nozzle is coated with a diamond-like carbon which makes it a high-performance nozzle designed for 3D printing applications that require durability and resistance to wear. The nozzle is made from hardened steel and features a Diamond-Like Carbon (DLC) coating, which significantly enhances its wear resistance, hardness, and low friction properties.

The DLC coating provides the nozzle with a surface that is extremely hard and resistant to abrasion, making it perfect for printing with abrasive materials like carbon fiber, metal-filled, or glass-filled filaments. Additionally, the low friction coefficient of the coating ensures smooth filament flow and reduces the risk of clogs or jams during the printing process.

By using a DLC Hardened Steel Nozzle, you can expect longer service life, consistent print quality, and less frequent nozzle replacements, even when working with abrasive filaments. This makes it a valuable addition to any 3D printer setup, particularly for users who regularly print with specialty materials that can wear down standard nozzles.
