Phaetus Rapido 2 Hotend  HF & UHF V6-Compatible High-Flow 1.75mm

Built for high-speed, reliable extrusion, the Phaetus Rapido Hotend 2 combines an aluminum heatsink, titanium heatbreak, and a plated-copper extended heatblock to create a long, efficient melt zone. The rigid structure uses a titanium alloy support screw and ships with a plated-copper nozzle, making Rapido 2 a robust upgrade for fast printing and demanding filaments.

Two performance options: Choose HF (High Flow) or UHF (Ultra High Flow). Both are V6-nozzle compatible, and the included extension hardware lets you quick-switch between HF and UHF when you need more flow. A planar ceramic heater and serviceable, removable thermistor streamline maintenance and heat-up, so you can spend more time printing and less time tinkering.

Note: Rapido 2 and Rapido 2 Plus share the same overall form factor but differ in sensor/heater details and temperature ceilings. See variant guidance below.

Key features

• Aluminum heatsink for strong heat dissipation

• Titanium heatbreak for excellent thermal isolation and fewer heat-creep issues

• Plated-copper extended heatblock for a longer melt zone and higher throughput

• Titanium alloy support screw for low heat conduction and high strength

• Plated-copper nozzle included

• HF & UHF variants, V6-nozzle compatibility, quick-switch design (adapter/extension hardware)

• PTC ceramic heater for rapid, even heating

• Removable thermistor for easy service

Variant guidance

• Rapido 2 (HF / UHF): PTC ceramic heater, removable 104NT-type thermistor, designed for high-flow printing; temperature ceiling of 280 C  

• Rapido 2 Plus (HF / UHF): same hotend but with a PT1000 thermistor and higher temperature ceiling of 350c UHF variant targets the highest volumetric flow.

• Interface: V6-style nozzle compatibility across variants. Always confirm mount, thread/seat, and clearances for your specific toolhead.

Setup tips

• After installation, PID tune and re-dial retraction/pressure advance.
  

• For abrasive filaments, pair with hardened drive components and keep the filament path clean and adjust printing temperature.
