Bondtech CHT Volcano High Flow Coated Brass Nozzle

Push your high-speed 3D printer to its absolute limits with the Bondtech CHT® Volcano Coated Brass Nozzle. Specifically engineered for extended Volcano-style heater blocks, this nozzle pairs an ultra-high thermal conductivity brass body with patented melt-splitting geometry to significantly boost your hotend's volumetric flow. Print larger layer heights, complete massive structural models faster, and build stronger functional parts with drastically improved layer-to-layer adhesion.

By maximizing thermal performance directly inside the melt zone, this nozzle acts as a drop-in speed upgrade—no bulky or expensive hotend modifications required.

🚀 Patented Core-Heating Technology (CHT)

Standard nozzles only transfer heat to the outer surface of your filament, leaving a cooler, semi-solid core. Bondtech’s patented CHT® technology solves this by splitting the single incoming filament strand into three separate, thinner channels. This dramatically increases the surface area exposed to the heated inner walls of the brass body, melting the plastic rapidly and evenly from the inside out.

• Unparalleled Flow Gains: Experience volumetric flow rate increases of 30% or more over standard Volcano configurations.
• Optimal Performance: For maximum volumetric flow gains, use nozzle diameters of 0.60mm or larger paired with rigid materials.

✨ Non-Stick Nickel Coated Protection

The premium, precision-machined brass body is treated with an advanced industrial Nickel coating. This surface layer delivers excellent protection and operational benefits:

• Slick Material Feed: Dramatically lowers the coefficient of friction, ensuring smooth, highly consistent plastic extrusion.
• Resists Filament Caking: Prevents sticky, molten plastic from adhering to the nozzle tip, keeping your toolhead clean and reducing cosmetic print defects.
• Enhanced Durability: Provides vital protection against corrosion, erosion, and mild abrasion to extend the working life of the brass substrate.

📋 Specifications & Compatibility

• Form Factor: Volcano Standard (M6x1 thread, 14.5mm thread length, 21mm total length). Fits all standard Volcano heater blocks.
• Base Material: Premium, high-conductivity brass with an ultra-smooth Nickel plating.
• Filament Compatibility: Optimized for 1.75mm; fully compatible with 2.85mm filaments and hotends.
• Available Sizes: 0.40mm, 0.60mm, 0.80mm, 1.0mm, and 1.2mm.
• Usage Tip: When swapping between highly contrasting materials (like transitions to flexible filaments), we recommend using dedicated nozzles to prevent residue build-up and minimize the risk of internal clogs.
