GammaMaster® Nozzle

The GammaMaster® Nozzle is the next evolution in nozzle technology, forged from the latest advancements in metallurgy and surface preparation technology. For too long, you have had to settle for poor thermal performance when printing with abrasive filaments, but GammaMaster is the best of both worlds. It's the first RepRap nozzle designed for abrasive filament printing that doesn't sacrifice thermal conductivity. Thermal Performance Crafted from a proprietary hardened alloy, the GammaMaster Nozzle features thermal performance similar to that of a standard brass nozzle while maintaining its abrasive-resistant qualities. GammaMaster is 2.7 times more thermally conductive when compared to hardened steel nozzles, meaning you no longer have to raise your nozzle temperature to print with abrasive filaments. Abrasion Resistant With a Limited Lifetime Warranty against abrasive wear, the GammaMaster Nozzle will print the entire gamut of thermoplastic materials. From basic PLA to glass fiber reinforced PEI, the GammaMaster Nozzle excels at printing abrasive filaments with a Rockwell C hardness level of 63. Anti-Adhesive Surface GammaMaster features our new Low Gamma™ coating that reduces the surface energy of the nozzle and prevents the accumulation of plastic around the nozzle's tip. With a measured surface energy of <30 dynes/cm, the Low Gamma coating allows for easier cleanup, fewer failed prints, and a better printing experience. Unlike PTFE-based coatings, GammaMaster’s surface is rated to high printing temperatures*, allowing you to reap the non-stick benefits with virtually any material. Multiple Geometries GammaMaster is available in three geometries: RepRap, AP3X, and Vase. Our RepRap geometry is the default nozzle geometry you're used to. AP3X adds 2 mm of tip length, making it ideal for belt printing and non-planar printing applications. Our Vase geometry is designed for vase mode prints with large layer lines—perfect for printed prosthetics, film props, and other large-scale prints. Best Warranty In The Business We are proud to offer a Limited Lifetime Warranty against abrasive wear for the GammaMaster Nozzle. Please note, certain exotic filaments, like Glow-in-the-Dark and Tungsten Carbide filled, are not covered under this warranty. For more information, read the full warranty here.
