Slice Engineering GammaMaster® Abrasion-Resistant Nozzle Set – 0.4 mm (5 pcs), Compatible with ARCO
- Built for Industrial-Grade Materials: Designed for the ARCO hotend, the GammaMaster® handles everyday favorites like PLA, PETG, and TPU with ease. Pair it with the PentaShield, and it confidently takes on demanding industrial-grade materials such as ABS, ASA, PET, PA, PC, and carbon- or glass-fiber reinforced polymers*.
- Exceptional Hardness: Crafted from a proprietary hardened alloy with a Rockwell C hardness of 63, the GammaMaster® is built to last. It’s ideal for high-strength, abrasive materials, including carbon fiber and glass fiber, giving you extended nozzle life and consistent results.
- Anti-Adhesive Surface: Its Low Gamma™ coating features a surface energy below 30 dynes/cm, preventing excessive filament buildup. This means less downtime, easier cleaning, and more time producing flawless prints.
- High Thermal Conductivity: With 2.7× better thermal conductivity than hardened steel, the GammaMaster® delivers heating performance on par with brass. The result? Stable extrusion and consistent print quality, even when working with industrial-grade abrasive materials.
