Phaetus Dragon Hotend UHF Ultra-High-Flow 1.75 mm Blue Built for speed , the Phaetus Dragon UHF hotend pairs a lengthened plated-copper heatblock with an extension nut to create a long melt zone for ultra-high extrusion flow. It’s available in 1.75 mm and is compatible with common V6-style interfaces, making it a strong upgrade for high-temperature and fiber-filled materials. Phaetus describes the UHF as “ultra-high flow.” You’ll see flow claims between ~45 mm³/s (Phaetus product copy) and up to ~70.5 mm³/s on some listings; real results depend on heater power, nozzle size, filament, and tuning Key features Extended melt zone design: lengthened plated-copper heatblock + extension nut for high throughput Thin-wall titanium heatbreak: excellent thermal isolation and reduced clogging risk High-temp, all-metal filament path: suited to engineering and abrasive materials (observe your printer’s heater and sensor limits) V6-interface compatibility: fits common V6-style nozzles Abrasive-ready: robust construction pairs well with composite filaments Setup tips Re-PID tune after installation; adjust retraction, pressure advance, and temperature to suit your filament. Ensure adequate heater power for high-flow printing; larger nozzles benefit most. For abrasive filaments, use hardened drive gears and keep the filament path clean. Heat-tighten nozzles to the manufacturer’s torque spec and follow safe installation practices. Show more
