Product Information
Full details
The Phaetus Dragonfly Hotend BMO is designed for 3D printing enthusiasts and professionals who require reliable, high-temperature performance from their machines. Its primary benefit is the all-metal construction that enables printing with advanced, abrasive, and high-temperature filaments up to 500 degrees Celsius, though users should be prepared for the calibration adjustments required when transitioning from standard PTFE-lined hotends.

FAQs
What is the maximum temperature of this hotend?
The Phaetus Dragonfly BMO is rated for temperatures up to 500 degrees Celsius.
Is this compatible with my Prusa i3 MK3S?
Yes, it is designed to be compatible with V6 hotend interfaces including those on the Prusa i3 MK3/MK3S.
Does this hotend use a PTFE liner?
No, the Dragonfly BMO is an all-metal design, which means there is no internal PTFE tubing exposed to the heating zone.
What nozzle type does this use?
It uses standard V6-style nozzles, and the package includes a high-quality 0.4mm plated copper nozzle.
Do I need to change my print settings?
Yes, all-metal hotends typically require reduced retraction settings (usually 0.5mm to 1.5mm) to prevent jamming.
Troubleshooting
Inconsistent filament flow
Check the PTFE tube inside the extruder (if applicable) or verify your retraction settings, as all-metal hotends require lower retraction distances.
Hotend jamming
Ensure the heat sink fan is running at 100% speed at all times and perform a cold pull to remove any debris from the nozzle.
Temperature fluctuations
Perform a PID autotune in your printer firmware to calibrate the new thermal mass of the copper alloy block.
Pros and Cons
Pros
- Superior thermal management with copper alloy construction
- High temperature threshold of 500°C
- Improved extrusion consistency due to low internal roughness
- Excellent heat sink dissipation
- Broad compatibility with popular printer ecosystems
Cons
- Requires professional-level installation knowledge
- Not suitable for beginners who have not mastered basic hotend maintenance
- May require updated firmware PID tuning
Setup, Compatibility & Care
Installation of the Dragonfly BMO should be performed with the printer powered off. Ensure the hotend is securely mounted to your extruder assembly using the provided fasteners. Because this is an all-metal hotend, you must perform a new PID tuning sequence in your firmware after installation to ensure stable temperature control. When changing nozzles, always heat the block to the printing temperature to ensure a proper seal. Regular maintenance involves cleaning the silicone sock of accumulated debris and checking the heat sink fan for dust buildup to maintain optimal airflow. Do not use metal brushes inside the nozzle, as this can degrade the precision surface finish.
