Supercharge your desktop 3D printer with the E3D Revo HTA-HF High-Flow High-Temperature Abrasive Nozzle. Engineered specifically for the revolutionary rapid-swapping E3D Revo ecosystem, these "HF HTA" nozzles combine advanced high-volumetric flow properties with specialized metallurgy. They are uniquely designed to run extreme engineering filaments—such as Carbon Fiber PEEK, Glass Fiber Nylon, and metal-filled composites—at much higher speeds without losing heat profile consistency.
The Revo HT-A High Flow nozzle is built like an industrial shield. Modeled closely after the premium ObXidian product class, it integrates a ultra-hardened steel core tip to resist physical abrasion inside a high-conductivity copper carrier. This copper core transitions seamlessly into a dedicated internal thermal spreader segment to accelerate heat energy transfer directly into the moving filament. The entire nozzle module is then coated in a premium layer of **Chromium Nitride**, providing high-level corrosion prevention, immense abrasive resistance, and premium non-stick characteristics when running temperatures up to 500°C.
Drop-In High Flow Form Factor
Achieve higher volumetric melt capacities without modifying your hardware payload. The Revo HF HT-A retains the exact same exterior footprint and physical profile as a standard Revo nozzle. This means you do not have to redesign custom toolhead mounts or print revised cooling fan shrouds. Inside, a unique custom geometry modifies the internal melt path structure, vastly expanding internal contact surface areas to maximize heat transmission directly to the core of your filament spool.
Key Features & Project Capabilities
Chromium Nitride Armor: High-hardness protective coating shrugs off highly abrasive carbon fiber strands while offering slick, non-stick exterior properties.
500°C Peak Engineering Threshold: Fully optimized to withstand ultra-high temperature engineering plastic extrusion profiles safely.
Integrated Heatbreak Unit: Preassembled factory construction bridges the nozzle tip and the titanium heatbreak into a single piece, completely eliminating the risk of plastic leaking or hot-tightening accidents.
Extended Sizing Choices: Unlocks greater print speeds for traditional 0.4mm, 0.6mm, and 0.8mm options, while opening massive extrusion sizes like 1.0mm, 1.2mm, and 1.4mm to your toolkit.
Rapid Visual Verification: Finished in a distinct gray colorway with deep, laser-engraved sizing text on the outer hex body for simple size parsing.
⚠️ Thermal limits and compatibility warnings:
HeaterCore Restrictions: While HF HT-A nozzles physically install onto standard 40W and 60W Revo HeaterCores, their temperature threshold will be strictly capped at 300°C. To unlock full high-temperature capabilities up to 500°C, you must upgrade to a dedicated Revo High Temperature Hotside Kit.
System Exclusions: Revo series modules are entirely incompatible with older V6-style threaded heater blocks.
Z-Axis Adjustment: Always re-calibrate your printer's digital Z-offset and first-layer leveling height after swapping individual nozzle units.
