Benefits 

The GammaMaster® Nozzle combines a hardened alloy with a Low Gamma™ coating to deliver exceptional wear resistance and long-lasting performance. Created by Florida-based Slice Engineering, its copper-based core ensures efficient heat transfer, making it the perfect choice for printing engineering-grade materials such as carbon fiber and fiberglass. 

  • 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*.  

*Performance may vary depending on filament and environment. For the best results, refer to filament specifications and the ARCO user manual for optimal settings. 

  • 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. 

  

Extreme Wear Test: 100× Longer Life Confirmed 

 

We put the ARCO with the GammaMaster® ultra-durable nozzle through one of the toughest challenges: nonstop printing with abrasive carbon fiber and glass fiber filaments..

  • Proven Ultra-Durability: The GammaMaster® handled 2000 g of abrasive filament with less than 3 μm of wear—that’s practically unchanged. 

  • Far Beyond Standard Nozzles: A regular brass nozzle wore down by 310 μm after printing just 100 g. 

  • Consistent, Long-Term Printing: Even under extreme stress, ARCO + GammaMaster® kept prints precise, stable, and reliable.
