Phaetus Hotends, Nozzles & Extruders – precise melting performance for high printing speeds
Phaetus stands for robust all-metal constructions with clear practical orientation: titanium heatbreaks for clean thermal separation, nickel-plated copper heating blocks for efficient heat transfer, and variants from standard to ultra-high-flow segments. The result: fast, reproducible extrusion – even with technical filaments and abrasive fillers.
Why Phaetus makes sense for you
- High flow rates: Models like Rapido 2 (HF/UHF) and Dragon (HF/UHF) are designed for high output volumes – ideal for higher layer heights, wide lines, and "speed profiles".
- Temperature & material range: All-metal design for broad material compatibility; UHF variants target high-temperature and fiber filaments.
- Fast, stable heating: optimized heating blocks and sensors ensure quick heating and steady temperature curves – the basis for consistent paths.
- Durable nozzle options: XG nozzles with M4 thread in brass, plated copper, or hardened steel noticeably reduce wear with CF/glow pigments.
Which series fits your application?
Rapido Hotend 2 (HF/UHF/Plus/2F): Focus on fast heat transfer, titanium heatbreak, "High-/Ultra-High-Flow" for speed setups. For users who want more throughput without modification.
Dragon Hotend (ST/HF/UHF): All-metal up to very high temperature ranges; ST for precision & quality at normal flows, HF/UHF for significantly increased material throughput.
XG / DropEffect: Lightweight hotend with M4 nozzle system; nozzles in brass (all-round), plated copper (best heat conduction), and hardened steel (abrasive compounds).
APUS / APUS 2 Extruder: Direct extruder with high torque reserve and grippy dual-drive – for precise feed control from TPU to CF-nylon.
Practical tips for clean results
- Choose nozzle diameter: 0.4 mm remains universal; 0.6–0.8 mm significantly speeds up parts – often the most efficient adjustment combined with HF/UHF hotends.
- Abrasive filaments: Always use hardened steel or plated copper nozzles for CF/glass/glow to avoid bore growth and dimensional deviations.
- Retraction & cooling: With bimetallic heatbreaks, shorter retraction distances and clean part cooling are often more effective than "more speed" alone.
Compatibility & setup
Many Phaetus hotends use common designs (e.g., V6 nozzle shape), which facilitates mounts and upgrades. Check the heater voltage (12/24 V), sensor type, and cable routing space before modification. Numerous mounts/adapters exist for Voron, Creality, Bambu & Co. – we are happy to advise you.
FAQ – brief & concrete
What is the difference between ST, HF, and UHF?
ST = standard flow focusing on surface quality; HF = high flow for higher output volumes; UHF = ultra-high flow for maximum throughput and high layer heights.
Which nozzle for CF filament?
Hardened steel or plated copper (wear-resistant, thermally conductive). Brass only for non-abrasive plastics.
Does an HF/UHF hotend alone already provide more speed?
It increases the potential. For real time savings, you need suitable slicer profiles (line width, layer height, flow), an appropriate nozzle, and sufficient heating power.
Our tip: Start with a 0.6 mm nozzle on an HF hotend and optimize line width & layer height. This way you get visibly shorter print times with stable part quality.
