Thermal Performance

With a unique proprietary hardened alloy, GammaMaster combines the resilience of an abrasive-resistant nozzle with the thermal efficiency of a standard brass nozzle. Enjoy 2.7 times superior thermal conductivity compared to hardened steel nozzles, eliminating the need for elevated nozzle temperatures when printing with abrasive filaments.

Abrasion Resistance

Backed by a Limited Lifetime Warranty for superior protection against abrasive wear, the GammaMaster Nozzle effortlessly handles a wide range of materials. From everyday PLA to robust glass fiber reinforced PEI, this exceptional nozzle excels in printing abrasive filaments with an impressive Rockwell C hardness level of 63.

Anti-Adhesive Surface

Slice’s innovative Low Gamma coating lowers the surface energy of the nozzle, preventing plastic buildup around the tip. With a surface energy measuring <30 dynes/cm, this advanced coating ensures effortless cleanup, minimizes print failures, and delivers superior printing performance. Unlike PTFE-based coatings, GammaMaster’s surface can withstand high printing temperatures*, providing you with exceptional non-stick benefits for a wide range of materials.

Multiple Geometries

Whether your hotend employs standard M6 x 1.0 threads, the GammaMaster Nozzle offers a perfect fit. The RepRap geometry, which is the default and familiar choice, caters to traditional 3-axis FDM printing. On the other hand, the AP3X geometry features a pointed shape with an additional 2 mm of tip length, specifically designed for belt printing and non-planar printing applications, providing unparalleled versatility.

Best Warranty In The Business

We take pride in offering this exceptional warranty; however, please note that certain exotic filaments such as Glow-in-the-Dark and Tungsten Carbide filled are not covered. If you’re exploring specialty filament printing, we recommend exploring our Vanadium™ Nozzle.
