Phaetus Dragonfly Hotend BMO — All-Metal, Copper-Alloy Core V6 nozzles 

The Phaetus Dragonfly BMO is an all-metal hotend built around copper-alloy core parts for rapid heat transfer and stable temperature control. Its signature conical heatbreak-to-heatsink interface increases contact area for improved heat dissipation and reduced heat-creep, supporting cleaner extrusion across a wide range of materials—including higher-temperature and abrasive filaments when paired with suitable nozzles. Rated up to 500 °C (limited by your heater and sensor), BMO drops into V6/groove-mount toolheads used on many popular printers and extruders.

Key features

• All-metal path with copper-alloy core for fast heating and stable temps. 

• Conical heatbreak/heatsink fit improves dissipation and mitigates jams. 

• High-temperature capable: up to 500 °C with appropriate heater/thermistor. 

• Smooth filament path: low-roughness heatbreak spec often cited for reliable feeding.

• V6/groove-mount compatibility for broad ecosystem support.

Compatibility notes

• BMO vs BMS: Functionally similar; BMO uses V6/groove-mount, while BMS targets Creality-style bolt-mount extruders/heatsinks. Choose based on your mount style.

• Verify heater/thermistor type, mount clearances, and nozzle thread/seat against your specific toolhead before install.

Setup tips

• After install, PID tune and re-dial retraction/pressure advance.

• For abrasive filaments, use a hardened or coated nozzle and maintain a clean filament path.

• Heat-tighten the nozzle per manufacturer torque guidance and confirm temperature sensor settings in firmware.
