Phaetus Dragonfly Hotend (BMO)

CoreXY and Voron builders often face heat dissipation challenges that cause inconsistent extrusion and print defects, especially when printing high-temperature or engineering-grade filaments. Without an efficient heat break and heatsink design, users risk clogs and under-extrusion that degrade print quality.

The Phaetus Dragonfly Hotend (BMO) is an all-metal hotend featuring a copper alloy construction for superior thermal conductivity, designed to handle a broad range of materials including PLA, PETG, Nylon, PC, and PEEK. Its conical heat break and heatsink connection improve heat dissipation compared to traditional hotends, reducing heat creep and enabling reliable high-temp printing. The BMO variant supports groove mount setups like Prusa or direct mount configurations such as Voron, making it versatile for CoreXY and Klipper-based builds. This hotend includes a V6 style 0.4mm copper-plated nozzle, silicone sock, and necessary tools, but requires separate purchase of heater cartridge and thermistor.

Why Upgrade?

• Improved heat dissipation reduces heat creep and clogs in high-temp filaments like PC and PEEK
• Compatible with groove mount and direct mount setups for versatile installation on Prusa MK4 and Voron 2.4
• All-metal copper alloy construction enhances thermal transfer for consistent extrusion
• Includes copper-plated 0.4mm nozzle optimized for a wide range of filaments
• Supports CoreXY and Klipper ecosystems requiring reliable high-performance hotends

Best For:

• Voron 2.4 and CoreXY builders upgrading to an all-metal hotend for high-temp printing
• Prusa MK4 users needing a groove mount hotend with superior heat conductivity
• Klipper users seeking reliable heat break performance to prevent under-extrusion
• Advanced users printing engineering filaments like Nylon, PC, and PEEK
• DIY enthusiasts customizing direct mount hotend setups

Pair With the Right Filament

This hotend’s all-metal design and excellent heat dissipation make it ideal for printing demanding engineering and high-temp filaments.

• ABS Filament — for durable, heat-resistant prints requiring stable extrusion
• Polycarbonate (PC) Filament — high-temp filament that benefits from superior heat break design
• Nylon Filament — flexible and strong filament needing consistent hotend temperature
