ALPHA Polycrystalline Diamond (PCD) Nozzle Engineered For Extremes ALPHA nozzles feature an encapsulated polycrystalline diamond insert with a smooth nickel-plated copper body. This premium combination provides advantages over standard nozzles in thermal conductivity, hardness, maximum printing temperature, thermal expansion, and friction. 212% Harder Than Tungsten Carbide For years, tungsten carbide has been regarded as the top choice material for abrasive material printing. Now, PCD is here to take the crown with a hardness of 5000 (Vickers HV), making the Alpha nozzle overqualified for printing the most demanding materials. 97.5% Less Friction Than Nickel Clogs and inconsistent flow kill uptime. ALPHA combines the ultra-low friction coefficient of PCD (0.01) with an internal mirror-polished finish to help filament feed smoothly through the melt zone—reducing buildup and improving reliability. 30% Higher Heat Transfer Than Copper Put heat where it matters most—right at the point filament exits the nozzle. With PCD thermal conductivity up to 500 W/m·K, ALPHA provides exceptional heat transfer, improving melt stability, flow consistency, and high-speed performance.
