Phaetus Rapido 2

Phaetus Rapido 2 is a compact, fast-heating hotend family for high-flow 1.75 mm printing. This black 24V listing covers HF and UHF builds, with standard Rapido Hotend 2 280 °C variants and Rapido Plus Hotend 2 350 °C PT1000 variants.

Why choose Rapido 2?

• Titanium heatbreak for thermal isolation and less heat creep than the original stainless heatbreak design.
• Aluminum heatsink + plated-copper extended heatblock for a longer melt zone and fast temperature response.
• HF and UHF options let you choose a shorter high-flow setup or the longer ultra-high-flow configuration when your toolhead clearance allows it.
• Removable temperature sensor makes service simpler: 104NT on the 280 °C Rapido Hotend 2, PT1000 on the 350 °C Rapido Plus Hotend 2.
• One-handed nozzle-change design with titanium alloy support screws to keep the heater block rigid.

• Nozzle ecosystem: V6-style nozzle compatible; pair with Phaetus plated-copper V6 nozzles or Phaetus hardened-steel V6 nozzles for spares.

Machine fitment and use

Rapido 2 is a strong fit for high-speed CoreXY builds and Voron-style toolheads where a Phaetus/Rapido mount is supported. It is commonly chosen for Voron V2.4, Trident, Switchwire, custom Klipper printers, and other machines that need more melt capacity without moving to a full toolhead swap. Keep a matching spare sock on hand: Rapido 2 HF silicone sock or Rapido 2 UHF silicone sock.

How to choose

• HF: choose this for a compact high-flow hotend when you want the simplest fit and do not need the longest melt zone.
• UHF: choose this when you are chasing higher volumetric flow and your toolhead has room for the longer setup.
• 280 °C / 104NT: choose standard Rapido Hotend 2 for common engineering plastics within its temperature range.
• 350 °C / PT1000 Plus: choose Rapido Plus Hotend 2 for higher-temperature materials and PT1000 sensor support.

Gotchas

• This is a hotend, not a complete toolhead or extruder kit.
• Confirm your printed mount, fan duct, wiring length, and firmware sensor type before installing.
• Run PID tuning after installation, then re-check retraction and pressure advance.
• For abrasive filaments, use a hardened or wear-resistant nozzle rather than the basic plated-copper nozzle.
