Phaetus Silicon Carbide Nozzles

Designed for high-performance extrusion systems, Phaetus Silicon Carbide (SiC) nozzles combine extreme material hardness with advanced thermal properties to meet the demands of professional and industrial-grade 3D printing. These nozzles are manufactured using sintered SiC ceramic, offering a hardness rating above 9.5 on the Mohs scale and thermal conductivity exceeding 170 W/m·K — ensuring rapid heat transfer and stable extrusion even under high-temperature conditions.

Key technical features:

• Material: Sintered Silicon Carbide (SiC) with ultra-low thermal expansion coefficient (≤4.0 × 10⁻⁶/K)
• Hardness: ≥9.8 Mohs — resists wear from abrasive filaments such as carbon fiber, glass fiber, metal-filled, and glow-in-the-dark composites
• Thermal Conductivity: >170 W/m·K — maintains consistent melt flow and reduces thermal lag
• Surface Finish: Sub-micron polishing with Ra < 0.2 μm — minimizes friction and filament drag
• Endcoat coating (except V6 variant): Achieve double wear-resistant protection and significantly extend service life.
• Temperature Resistance: Stable up to 300°C (550 °C for V6 variant) — suitable for engineering-grade polymers including PEEK, PEI, and PPS
• Chemical Resistance: Inert to acids, alkalis, and most solvents — ideal for chemically reactive or hygroscopic materials

These nozzles are precision-machined to ensure concentricity and dimensional accuracy, reducing stringing and improving layer adhesion. The non-stick surface and low thermal inertia help maintain clean extrusion paths and reduce clogging, even during long prints with composite filaments.

Compatible with:

• Prusa Nextruder systems (e.g., MK4, XL, MK3.9)
• Creality K2 Plus/Hi
• Creality K1C/K1Max/Ender-3 V3/Ender-3 V3 Plus
• PS series hotends with V6 (M6) thread interface

Available in multiple nozzle diameters (0.4 mm, 0.6 mm) to support fine-detail prototyping and high-flow production. Ideal for prosumers, dental labs, and design firms requiring consistent output and minimal maintenance.
