HF HT - A nozzles are top - notch high - temperature, high - flow, and abrasion - resistant nozzles. Just like ObXidian, they feature a hardened steel tip, a copper carrier, and a copper spreader segment. This design optimizes heat transfer to the heatsink. The nozzles are coated with Chromium Nitride, offering abrasion resistance, extra corrosion prevention, and non - stick properties for printing up to 500°C. When used with 40W & 60W HeaterCores, the temperature is limited to 300°C. To reach 500°C, upgrade to a Revo High Temperature Hotside kit. Revo HF HT - A boosts your setup's volumetric flow rate, allowing you to print high - temperature, abrasive materials faster. It has the same form factor as standard Revo HotEnds, so no need to adjust your existing mounts and fan ducts. These high - flow nozzles use a unique internal geometry to improve thermal transfer to the filament. It unlocks higher flow for 0.4mm, 0.60mm, and 0.80mm nozzle sizes and adds 1.00mm, 1.20mm, and 1.40mm sizes. You can freely experiment with different nozzles for various applications. If a nozzle gets clogged, simply unscrew it and replace it easily, reducing your 3D printer's downtime. Each Revo Nozzle is a pre - assembled unit of nozzle and HeatBreak, eliminating hot tightening and assembly errors. Say goodbye to HotEnd leaks and enjoy reliable 3D printing. The HF HT - A nozzles are grey and have clearly engraved size numbers for easy identification. Note that Revo™ Nozzles are not compatible with V6 - style HeaterBlocks, and you may need to adjust your Z offset when changing nozzles.
Using these E3D Revo HF HT - A nozzles is quite simple. First, make sure your 3D printer setup is compatible. If you want to print at up to 500°C, you'll need to upgrade to a Revo High Temperature Hotside kit. When using with 40W or 60W HeaterCores, the max temperature is 300°C. Since the nozzles have the same form factor as standard Revo HotEnds, you don't have to change your existing mounts and fan ducts. You can freely experiment with different nozzle sizes for different printing needs. If a nozzle gets clogged, just unscrew it and put in a new one. Remember, these nozzles are pre - assembled, so there's no need for hot tightening or worrying about incorrect assembly. For maintenance, keep them clean and dry. Check the engraved size numbers regularly to ensure you're using the right nozzle. And be aware that Revo™ Nozzles don't work with V6 - style HeaterBlocks, and you might need to adjust the Z offset when you change nozzles.
