The Phaetus Dragonfly is an all-metal hotend, which mainly consists of copper alloy for better thermal conductivity. Depending on the heating cartridge, the hotend can be heated up to 500 ° C. Therefore, with the Dragonfly Hotend, it is possible to process a wide variety of high-temperature materials and abrasive materials thanks to the all-metal design. Due to the conical connection of the heat break and heat sink, the hot end has far better heat dissipation than conventional hot ends. The internal hole roughness (≤ Ra0.3) and the precise production tolerances also improve the print quality and enable an even filament flow. Features Temperature resistance up to 500 ° C All-metal design Good heat dissipation Even filament flow Characteristics: Full metal High-temperature application (up to 500 ° C) Easy exchange Incl.

Documentation: https://github.com/Phaetus/Dragonfly-BMS Manufacturer Specification: Drgonfly Hotend_BMS Features All-metal kit, with overall high temperature resistance up to 500 ℃. The hotend is mainly composed of copper alloy material, which has the advantage of faster heating and better heat dissipation. Conical fitting of heatbreak and heatsink makes a perfect heat dissipation. The inner hole roughness of heatbreak Ra≤0.3, which allow a more smooth movement of filament, resulting a higher resolution prints.
