Ceramic heating pads replace the conventional cartridge\n  heater. A thicker titanium alloy heatbreak replaces the thin-wall stainless steel\n  tube. The result is a hotend that heats faster, weighs less, handles abrasive\n  filaments longer, and delivers up to \u003cstrong\u003e74 mm³\/s volumetric flow\u003c\/strong\u003e\n  with the Melt Zone Extender (MZE) installed — while remaining compatible with\n  V6 and Dragon toolhead mounts.\n\u003c\/p\u003e\n\n\u003cp\u003e\n  ⚠️ \u003cstrong\u003eHot tightening required.\u003c\/strong\u003e Always final-tighten the nozzle\n  at operating temperature to prevent leaks.\u003cbr\u003e\n  ⚠️ \u003cstrong\u003eHeatblock is 8.5mm longer than the original Dragon.\u003c\/strong\u003e\n  Fan duct outlet and probe height may need to be adjusted if you're mounting\n  in a toolhead designed for the standard Dragon. Volcano-specific fan duct and\n  probe mounts resolve this. Spacer included for original Dragon mounts — see\n  compatibility notes below.\u003cbr\u003e\n  ⚠️ \u003cstrong\u003eNozzle thread: V6 style, 7.5mm thread length only.\u003c\/strong\u003e\n  Standard V6 nozzles (6mm thread) will not seat correctly in the Dragon ACE.\n\u003c\/p\u003e\n\n\u003ch3\u003eCeramic Heating Pad — Faster Heat-Up, Lighter Weight, Easier Replacement\u003c\/h3\u003e\n\u003cp\u003e\n  The original Dragon uses a conventional 6mm cartridge heater — a cylindrical\n  resistive element that inserts into the heatblock and makes contact over a\n  curved surface. The Dragon ACE replaces this with a\n  \u003cstrong\u003eceramic heating pad\u003c\/strong\u003e — a flat resistive element that contacts\n  the heatblock across a defined flat surface. The contact geometry is more\n  consistent cartridge-to-cartridge than a round cartridge seated in a round bore,\n  which means more predictable heat transfer and more uniform block temperature.\n  Ceramic pads also have a \u003cstrong\u003elower thermal mass\u003c\/strong\u003e than cartridge\n  heaters of comparable power — they reach target temperature faster, respond\n  to PID corrections faster, and are easier to replace when damaged because\n  they don't require pulling a press-fit cylinder from a bore. The net effect\n  is a heatblock that is both \u003cstrong\u003elonger than the original Dragon's\u003c\/strong\u003e\n  (for the increased melt zone needed for higher flow) and\n  \u003cstrong\u003e10 grams lighter\u003c\/strong\u003e than the original Dragon complete with\n  heating element included.\n\u003c\/p\u003e\n\n\u003ch3\u003e74 mm³\/s Maximum Flow — Dragon HF Throat + Volcano-Style Heatblock\u003c\/h3\u003e\n\u003cp\u003e\n  The Dragon ACE achieves its flow rate by combining two proven geometries:\n  the \u003cstrong\u003eoriginal Dragon HF throat design\u003c\/strong\u003e — with its precisely\n  machined inner bore (≤ Ra0.3 roughness) that minimizes flow resistance —\n  with a \u003cstrong\u003evolcano-style elongated heatblock\u003c\/strong\u003e that extends the\n  active melt zone significantly beyond a standard Dragon block. With the optional\n  \u003cstrong\u003eMelt Zone Extender (MZE) installed\u003c\/strong\u003e, the total hot-side length\n  reaches 40mm and maximum practical flow reaches \u003cstrong\u003e74 mm³\/s\u003c\/strong\u003e\n  (tested with PETG through a 1.2mm nozzle — see the documentation link below\n  for the full test report). Without MZE, the Dragon ACE still delivers\n  substantially higher flow than the original Dragon in the same form factor.\n\u003c\/p\u003e\n\n\u003ch3\u003eTitanium Alloy Heatbreak — Thicker Wall, Better Abrasion Resistance\u003c\/h3\u003e\n\u003cp\u003e\n  The original Dragon uses a thin-wall stainless steel heatbreak tube — excellent\n  thermal isolation, but thin-wall steel is vulnerable to abrasive wear when\n  running fiber-filled composite filaments regularly. The Dragon ACE upgrades\n  this to a \u003cstrong\u003etitanium alloy heatbreak\u003c\/strong\u003e that is thicker-walled\n  than the stainless alternative. Titanium's combination of low thermal\n  conductivity (needed for the sharp thermal gradient), high mechanical strength,\n  and significantly better abrasion resistance makes it the correct material\n  for sustained printing with PLA-CF, PA-CF, PA-GF, and other abrasive\n  composites that would eventually score a standard steel heatbreak.\n\u003c\/p\u003e\n\n\u003ch3\u003eOne-Handed Nozzle Changes — The Signature Dragon Feature, Preserved\u003c\/h3\u003e\n\u003cp\u003e\n  The Dragon ACE retains the low-conductivity titanium retention screws that\n  define the Dragon nozzle-change experience. The heatblock stays cool enough\n  at the screw positions to handle without burning, allowing the nozzle to be\n  swapped single-handed without tools or hot tightening at installation —\n  just the final hot-tighten to seal. The Dragon ACE uses\n  \u003cstrong\u003eV6-style nozzles with 7.5mm thread length\u003c\/strong\u003e — verify this\n  spec before ordering replacement nozzles, as standard V6 nozzles use 6mm thread\n  and will not seat correctly.\n\u003c\/p\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n
