Phaetus PS SiC nozzle 0,4 mm

Product Description

The Phaetus PS SiC nozzle 0,4 mm is an elite, industrial-grade extrusion component designed for absolute precision, unyielding durability, and extreme wear resistance under the most demanding workshop conditions. Utilizing a core tip machined from 99.9% high-purity Silicon Carbide (SiC), this premium nozzle delivers an incredible Mohs hardness rating of 9.8. This makes it up to 7 times more durable than conventional hardened steel nozzles, ensuring your machine can handle the most abrasive filaments without suffering from orifice widening, tip flattening, or dimensional deviation over thousands of print hours.

In addition to its exceptional material hardness, Silicon Carbide boasts a high thermal conductivity of 170W/m·k, matching the thermal performance of classic brass. This allows the Phaetus PS SiC nozzle 0,4 mm to act as a seamless, drop-in replacement that retains your favorite slicing profiles without needing massive temperature adjustments. The entire nozzle body is finished with a state-of-the-art DLC (Diamond-Like Carbon) coating, reducing the surface friction coefficient down to a mere 0.05. This ultra-smooth coating actively prevents molten plastic accumulation, keeping the tip clean and completely eliminating exterior wall artifacts caused by dragged filament residue.

Engineered with an exceptional internal roughness rating lower than Ra0.2, this 0,4 mm nozzle significantly reduces feeding resistance, lowering extrusion pressure and protecting your extruder gears from skipping. It handles extreme operating limits up to 550°C in continuous use, making it fully compatible with everything from everyday PLA and PETG to high-temperature aerospace materials like PEEK and PEI. Precision machined to a strict concentricity tolerance of 0.02mm, this V6-style M6 threaded component is the definitive, long-term tooling upgrade for high-speed motion systems like the Voron Trident or custom desktop CNC setups.

Key Features

• 99.9% Pure Silicon Carbide Tip: Features a hyper-hard Mohs 9.8 ceramic core insert that guarantees complete resistance against aggressive abrasive filaments.

• Refined Anti-Stick DLC Coating: Finished with a protective Diamond-Like Carbon film that eliminates plastic bonding, preserving outer tip geometry and cleanliness.

• 550°C Maximum Operating Limit: Built to endure intense industrial thermal processing zones and heated chambers without structural compromise.

• High Thermal Conductivity: Delivers an outstanding 170W/m·k heat transfer profile, mimicking brass properties for uniform filament melting.

• Mirror-Smooth Internal Channel: Features an ultra-low inner roughness profile ($\le\text{Ra0.2}\mu\text{m}$) that minimizes backpressure, clogs, and friction during high-speed runs.

Applications

• Upgrading the primary toolhead on high-acceleration Voron, CoreXY, and custom 3D printers that employ V6-style standard M6 heater blocks.

• Continuous production of industrial parts using fiber-reinforced composites (like Carbon Fiber ABS, Glass Fiber ASA, or Kevlar Nylon).

• Formulating high-detail engineering prototypes out of metal-filled, glow-in-the-dark, and ceramic-loaded matrices without tip degradation.
