Description

Phaetus Silicon Carbide Nozzle for Creality K1C / K1 Max / Ender-3 V3

The Phaetus Silicon Carbide nozzle for the Creality K1C platform combines silicon carbide — with a Mohs hardness of 9.8, just below diamond — with Phaetus’s patented EndCoat™ coating for dual wear-resistant protection. The result is a nozzle that lasts up to 7 times longer than standard hardened steel, handles every abrasive filament on the market, and integrates seamlessly with the K1C’s quick-swap system.

If you’re printing carbon fibre, glass fibre, metal-fill, or wood-fill on your K1C and going through hardened steel nozzles faster than you’d like, this is the upgrade that dramatically extends your replacement interval.

Dual Wear Protection — SiC + EndCoat™

Silicon carbide alone is one of the hardest materials used in nozzle manufacturing. Adding EndCoat™ on top creates a dual-layer defence — the SiC body resists bore wear from abrasive particles flowing through, while the EndCoat™ surface treatment protects the nozzle tip and exterior from buildup and thermal degradation. Together, they deliver 7× the service life of standard hardened steel.

The inner bore roughness is below Ra 0.4, ensuring smooth filament flow with minimal adhesion and residue buildup inside the nozzle.

Available Sizes

0.4 mm

The standard all-rounder. Best balance of detail and speed for everyday printing across all materials including carbon fibre and glass fibre composites.

0.6 mm

Higher throughput for fast functional prints. Recommended for abrasive CF and GF filaments where the wider bore reduces clogging risk while maintaining good detail.

SiC vs EndCoat™ vs Standard Hardened Steel

Standard Hardened Steel (Stock K1C Nozzle)

Baseline abrasion resistance with bimetallic copper/hardened steel construction. Wears noticeably with heavy CF/GF printing.

Phaetus EndCoat™ Hardened Steel

HV3300 coated surface — 2.5× longer life than standard hardened steel. Mid-range upgrade.

Phaetus Silicon Carbide (This Product)

Mohs 9.8 + EndCoat™ — 7× longer life than standard hardened steel. The ultimate option for heavy abrasive filament users who want maximum nozzle lifespan.

Quick-Swap Installation

Compatible with the K1C’s tool-free quick-swap nozzle system. Heat the nozzle, release the mechanism, swap, and lock. Under a minute, no tools.
