The HT-A uses \u003cstrong\u003eChromium Nitride (CrN)\u003c\/strong\u003e instead, which\n  is specifically engineered for sustained operation at temperatures that would degrade\n  DLC coatings. CrN delivers three simultaneous benefits on a single surface treatment:\n  \u003cstrong\u003eabrasion resistance\u003c\/strong\u003e against fiber-filled and particle-loaded filaments,\n  \u003cstrong\u003ecorrosion resistance\u003c\/strong\u003e for chemically aggressive materials, and\n  \u003cstrong\u003enon-stick properties\u003c\/strong\u003e that reduce filament build-up on the nozzle tip.\n  The result is a grey-colored nozzle visually distinct from other Revo variants — you\n  won't confuse an HT-A with a brass or ObXidian nozzle at a glance.\n\u003c\/p\u003e\n\n\u003ch3\u003eTri-Metal Construction — Hardened Steel Tip, Copper Carrier, Copper Spreader\u003c\/h3\u003e\n\u003cp\u003e\n  The HT-A's construction follows the same architecture as ObXidian but optimized for\n  high-temperature use. A \u003cstrong\u003ehardened steel tip\u003c\/strong\u003e forms the wear surface at\n  the orifice — the point of highest abrasive contact with the filament. Behind it, a\n  \u003cstrong\u003ecopper carrier and copper spreader segment\u003c\/strong\u003e maximize thermal conductivity\n  between the HeaterCore and the tip, ensuring consistent heat delivery at high temperatures\n  where thermal lag becomes a real problem. Copper's thermal conductivity is significantly\n  higher than steel — this tri-layer approach gives you the hardness of steel where it\n  matters and the heat transfer of copper everywhere else.\n\u003c\/p\u003e\n\n\u003ch3\u003eHigh-Flow Internal Geometry — Same Form Factor, Higher Throughput\u003c\/h3\u003e\n\u003cp\u003e\n  Unlike E3D's legacy high-flow solutions (Volcano, SuperVolcano), which required longer\n  heatblocks and different mounts, the HF HT-A achieves increased volumetric flow by\n  modifying the \u003cstrong\u003einternal channel geometry\u003c\/strong\u003e — increasing heat-transfer\n  surface area inside the nozzle without changing the external dimensions. Same Revo\n  form factor, same mount, same fan duct, same toolhead clearances. You gain higher\n  flow throughput for fast printing of high-temperature engineering materials with zero\n  hardware reconfiguration.\n\u003c\/p\u003e\n\n\u003ch3\u003eSix Nozzle Sizes — Including Large Bore for High-Flow Draft and Industrial Applications\u003c\/h3\u003e\n\u003cp\u003e\n  Standard Revo nozzle ranges stop at 0.8mm. The HF HT-A extends to\n  \u003cstrong\u003e1.0mm, 1.2mm, and 1.4mm\u003c\/strong\u003e — making it the correct choice for\n  draft-quality functional parts at maximum speed, thick-wall structural printing,\n  and industrial-grade composite filaments where large particles require large orifices\n  to prevent jams. The full size range with abrasion resistance and 500°C capability\n  in a single nozzle family covers essentially every high-performance printing use case:\n\u003c\/p\u003e\n\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e0.4mm\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDetail and precision — CF\/GF composites, high-temp engineering grades\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e0.6mm\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBalanced speed\/detail — standard engineering material workhorse size\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e0.8mm\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHigh-speed printing — thick walls, structural parts, draft quality\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e1.0mm\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUltra-high flow — large functional parts, heavily filled composites\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e1.2mm\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIndustrial draft — maximum layer height, thick-section parts\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e1.4mm\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMaximum bore — ultra-coarse printing, large particle composite filaments\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eRevo RapidChange — Nozzle + HeatBreak as One Unit, No Hot Tightening Ever\u003c\/h3\u003e\n\u003cp\u003e\n  Every Revo nozzle is a \u003cstrong\u003epre-assembled nozzle and HeatBreak in a single sealed\n  unit\u003c\/strong\u003e. This design eliminates the fundamental failure mode of conventional\n  hotends: the nozzle-to-heatblock joint that requires hot tightening to seal and\n  inevitably leaks when under-torqued, over-torqued, or thermally cycled repeatedly.\n  With HT-A, you twist it in at room temperature with your fingers — the geometry of\n  the assembly creates the seal, not torque. No leaks. No burns. No failed assemblies.\n  When you need to swap sizes or replace a clogged nozzle, it takes 30 seconds and\n  zero tools.\n\u003c\/p\u003e\n\n\u003ch3\u003eRapid Identification — Grey Body, Engraved Size\u003c\/h3\u003e\n\u003cp\u003e\n  HT-A nozzles are \u003cstrong\u003egrey in color\u003c\/strong\u003e, visually distinguishing them from\n  Revo brass (gold), ObXidian (black), and standard HT (also grey but without the HF\n  geometry).
