Phaetus Silicon Carbide Nozzle

High-temperature 3D Printing Nozzle

Filament Diameter: 1.75mm

Overview

The Phaetus Silicon Carbide Nozzle is engineered for makers who push their printers far beyond standard materials. Built from ultra-pure SiC and finished with a low-friction DLC coating, this nozzle delivers exceptional wear resistance, stable thermal performance, and consistent extrusion when printing abrasive or high-temperature engineering filaments.
Whether you’re running carbon-fiber blends, glass-filled polymers, or demanding production grade materials, this nozzle maintains dimensional accuracy long after brass and hardened steel have worn out.

Key Features

Ultra-hard Silicon Carbide body
Maintains precise orifice geometry even under continuous use with abrasive filaments.

DLC (Diamond-Like Carbon) coating
Reduces friction, improves flow consistency, and minimizes buildup during long prints.

High-temperature capability
Rated for extreme printing environments up to 550°C, suitable for advanced materials.

Exceptional thermal stability
SiC’s high thermal conductivity supports uniform melt behavior and predictable extrusion.

Precision manufacturing
Tight tolerances ensure smooth filament pathing and reliable layer deposition.

Ideal For

Carbon-fiber reinforced filaments (CF-PETG, CF-Nylon, CF-ASA)
Glass-filled materials
Abrasive composites
High-temperature polymers
Production environments requiring long-term dimensional stability

Why Upgrade to Silicon Carbide

If you print abrasive materials regularly, brass nozzles deform quickly and hardened steel eventually loses precision. Silicon Carbide offers a long-life alternative that preserves dimensional accuracy, reduces maintenance, and improves print consistency over time.
