Upgrade your 3D printing setup with the Ender-3 V3/K1C/K1 Max Hardened Steel Nozzle, the ultimate solution for makers who demand strength, precision, and reliability when working with abrasive filaments. Whether you’re printing with carbon-fiber, wood, metal-filled, or glow-in-the-dark filaments, this nozzle delivers consistent performance and extended lifespan even under challenging conditions.
Ultra-Durable Hardened Steel Construction
Crafted from premium hardened tool steel, this nozzle is built to resist wear from abrasive filaments that quickly erode standard brass or plated nozzles. Ideal for advanced materials that require toughness and longevity.
High Temperature Resistance
With excellent thermal stability, the hardened steel nozzle can withstand higher printing temperatures, maintaining consistent extrusion when working with engineering-grade materials like PETG-CF and PA-CF.
Smooth Filament Flow
Engineered with precision-machined internal channels to ensure smooth and stable extrusion. This reduces clogging and promotes reliable flow even with complex composite filaments.
Optimized Heat Distribution
Balanced heat transfer ensures even filament melting, producing accurate layer bonding and high-quality surface finishes on every print.
Versatile Compatibility
Fully compatible with Ender-3 V3, K1C, and K1 Max printers, making it easy to upgrade your existing setup without modifications.
Available in Multiple Sizes
Choose from different nozzle diameters to match your printing style—from fine-detail models to fast, high-flow prints.
Easy Installation and Replacement
Simple to swap in and out, allowing quick transitions between nozzle types for different projects or filament types.
When it comes to abrasive filaments like carbon-fiber, wood, or metal-infused materials, durability is key. The Ender-3 V3/K1C/K1 Max Hardened Steel Nozzle delivers the strength needed to maintain precise extrusion over long printing sessions—minimizing wear, maximizing consistency, and reducing downtime.
This nozzle ensures stable heat distribution, superior layer adhesion, and smooth extrusion, giving every print a professional finish that can stand the test of time. Whether you’re a professional engineer, hobbyist, or educator, it’s an essential upgrade for long-term reliability.
