Designed for builders and speed printers who have already\n  hit the volumetric ceiling of a standard hotend, the Dragon UHF combines an elongated plated-copper\n  heatblock with a volcano-style extension nut to create one of the longest melt zones available in a\n  V6-footprint hotend — capable of up to \u003cstrong\u003e45 mm³\/s\u003c\/strong\u003e (Phaetus official rating), with\n  real-world configurations reporting up to 70.5 mm³\/s depending on heater power, nozzle size, and\n  tuning.\n\u003c\/p\u003e\n\n\u003cp\u003eAvailable in \u003cstrong\u003eBlue or Black\u003c\/strong\u003e.

When filament can't liquefy fast\n  enough, you get under-extrusion, skipped steps, and failed prints — no matter how fast your\n  motion system moves. The Dragon UHF solves this at the source. Its elongated plated-copper\n  heatblock — matched with a volcano-style extension nut — dramatically increases the length of the\n  active melt zone, giving filament more dwell time at temperature. The result is a hotend that\n  keeps up with fast CoreXY and belt-driven printers without sacrificing extrusion consistency.\n  This is the upgrade that unlocks the actual speed potential of your printer.\n\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/www.phaetus.com\/cdn\/shop\/files\/UHF2.png?v=1686131891\" alt=\"Phaetus Dragon UHF hotend exploded view — elongated heatblock, volcano extension nut, and titanium heatbreak components\" style=\"width:100%;height:auto;\"\u003e\n\n\u003ch3\u003eTitanium Alloy Heatbreak — 0.25 mm Wall for Maximum Thermal Isolation\u003c\/h3\u003e\n\u003cp\u003e\n  Heat creep is the silent killer of high-speed printing. When heat migrates up the heatbreak into\n  the cold zone, filament softens prematurely, jams accumulate, and print quality degrades.\n  The Dragon UHF uses a \u003cstrong\u003etitanium alloy heatbreak with an ultra-thin 0.25 mm wall\u003c\/strong\u003e,\n  providing exceptional thermal isolation between the hot and cold ends of the assembly. Thinner\n  walls mean less material conducting heat upward — a sharper thermal gradient, more reliable\n  retraction, and significantly reduced clogging risk, especially at sustained high speeds.\n\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/www.phaetus.com\/cdn\/shop\/files\/UHF3.png?v=1686131891\" alt=\"Phaetus Dragon UHF titanium heatbreak detail — 0.25mm ultra-thin wall thickness for superior thermal isolation\" style=\"width:100%;height:auto;\"\u003e\n\n\u003ch3\u003eOne-Handed Nozzle Changes — Low-Conductivity Titanium Screws\u003c\/h3\u003e\n\u003cp\u003e\n  Nozzle swaps on most hotends require two tools and risk burning your fingers on the heatblock.\n  The Dragon UHF uses \u003cstrong\u003elow thermal conductivity titanium retention screws\u003c\/strong\u003e that stay\n  cool enough to handle during nozzle changes — allowing safe, controlled swaps without fully\n  disassembling the toolhead.
