As reinforced filaments containing carbon fiber, glass, and metal fillers become more common in modern 3D printing, nozzle wear has become a major performance challenge. Traditional brass nozzles quickly degrade when exposed to these abrasive materials, leading to inconsistent extrusion, dimensional drift, and frequent replacement.
DiamondBack™ nozzles solve this problem with proprietary, patented Polycrystalline Diamond (PCD) technology. Known for its extreme hardness, outstanding abrasion resistance, and exceptional thermal conductivity, PCD provides the durability and heat transfer needed for consistent, high-quality extrusion. These properties allow the nozzle to efficiently transfer heat from the hotend to the filament while maintaining precise geometry over extended print cycles.
The result is a high-performance nozzle capable of printing everything from standard PLA and ABS to highly abrasive composite filaments—without frequent nozzle changes. Proven in demanding industrial applications, PCD has demonstrated tool life improvements of 2–8× over tungsten carbide and other hard metals, delivering longer service life, reliable performance, and greater confidence in every print
