With a remarkable Rockwell C hardness level of 63, the GammaMaster ensures durability and reliability in demanding printing applications. However, it is important to note that certain filaments, such as glow-in-the-dark or tungsten carbide filled materials, are not covered under this warranty. For those interested in specialty filament printing, Slice Engineering recommends considering the Vanadium™ nozzle, which is specifically designed to handle such challenging materials.

Exceptional thermal performance

The GammaMaster nozzle is also engineered to deliver exceptional thermal performance thanks to its unique proprietary hardened alloy, an innovative design that give the GammaMaster nozzle the thermal efficiency typically associated with standard brass nozzles. With an impressive thermal conductivity that is 2.7 times superior to that of hardened steel nozzles, the GammaMaster allows for effective printing without the need for elevated nozzle temperatures when working with abrasive filaments.

Its advanced Low Gamma coating withstands temperatures up to 380 ºC, while the nozzle itself can handle temperatures reaching 500 ºC, making it an ideal solution for a wide variety of high-performance printing applications. This combination of thermal efficiency and resilience ensures consistent, high-quality results across diverse materials.

Advanced anti-adhesion coating

The GammaMaster nozzle features the Slice Engineering innovative Low Gamma coating, which significantly reduces the surface energy of the nozzle to below 30 dynes/cm. This helps prevent plastic buildup around the tip, ensuring effortless cleanup and minimizing the likelihood of print failures without compromising on temperature resilience.

Unlike traditional PTFE-based coatings, the GammaMaster’s surface can withstand high printing temperatures, making it suitable for a wide range of materials. This unique combination of low adhesion and high thermal tolerance ensures consistent, reliable results, allowing users to focus on creativity and precision in their 3D printing endeavors.

Versatility of geometries and diameters

The GammaMaster nozzle offers an extensive range of diameters and geometries, ensuring compatibility and versatility for various 3D printing applications. The RepRap M6 version (0.2 mm to 1.8 mm) is designed to fit standard M6 x 1.0 threads and it caters to users of traditional 3-axis FDM printers with its RepRap geometry. For those exploring more advanced techniques, the AP3X geometry (0.4 mm, 0.6 mm and 0.8 mm) features a pointed shape and an additional 2 mm of tip length, making it ideal for belt printing and non-planar applications.
