This hotend is really awesome. It preforms very well with a very short melt zone. Without the UHF extension I can get ABS to achieve ~25mm3/s with amazing reactions @ 0.4 with Galileo 2. Same heat up time as Rapido V2. The UHF extension is where things kinda fall apart. I can get ~32mm3/s but retractions are 0.8mm but still is wispy. It also take a 2 1/2 minutes to reach 260c This is a great hotend with the extension but the Rapido is much better when the extension is installed. This hotend is the same exact dimensions as the Pheatus Dragon without the UHF and can use the Dragon StealthBurner Printhead. When the UHF is install it is same height a the Rapido but does not tapper to the top and cannot use the Rapdio Printhead. This is a link to a modified Rapdio printhead which will support the UHF extension. https://www.printables.com/model/821299-drop-effectphaetus-next-g-uhf-stealth-burner-print I will be running with a CHT and not the UHF because I get better retractions and good enough volume for my printer. I really like it just wish it was easier to find the information for it. It will not be on Phaetus's website but directly on Drop Effect's website.

Ultra-high-flow 104NT hotend for speed-focused 1.75 mm printers. The Phaetus / DropEffect neXt G 104NT uses a ceramic heating plate, V6 nozzle interface, and Dragon-style footprint for high-flow extrusion without forcing a full toolhead redesign.
Why this over a standard hotend?
- Up to 45 mm³/s published flow target with the UHF groove adapter installed.
- Rigid kinematic coupling locks the heater block to reduce bending and help protect the heatbreak during nozzle changes or print strikes.
- V6-style nozzle compatibility keeps nozzle sourcing simple; pair it with our Phaetus copper-plated V6 nozzles or Phaetus hardened-steel V6 nozzles.
- Dragon-style mounting footprint fits many Voron, Creality, and Dragon-compatible toolhead mounts; Prusa use is supported with the included groove-mount adapter.
Specifications
- Model: DropEffect neXt G UHF hotend, red 104NT version
- Filament: 1.75 mm
- Thermistor: 104NT
- Nozzle temperature: 280°C+
- Maximum flow target: up to 45 mm³/s
- Size: 52.4 × 23 × 30 mm
- Net hotend weight: about 40 g
- Nozzle interface: V6-compatible; includes 0.4 mm and 0.6 mm plated copper nozzles
- Heatbreak: all-metal
Fitment and use
Use this for fast PLA, ABS, PETG, and similar high-flow builds where you want Dragon-style mount compatibility and V6 nozzle choice. It is a natural fit for Voron toolheads that support Dragon-style hotends, Prusa MK2/MK3-style groove-mount conversions, and Creality setups with the right adapter.
Gotchas
- This is the 104NT / 280°C+ neXt G version, not the PT1000 Fiber version.
- For sustained abrasive CF/GF work, use an appropriate hardened nozzle; the standard kit includes plated copper nozzles.
- Firmware must be configured for the 104NT thermistor, followed by PID tuning and retraction / pressure-advance tuning after installation.
- Some compact toolheads need adapter or wire-clearance checks because the heater and thermistor leads protrude from the assembly.
Verified buyer note: “This hotend is really awesome… with a very short melt zone… same exact dimensions as the Phaetus Dragon without the UHF.”
