Phaetus Rapido (Rapido 2) Hot End (Hotend) - UHF / HF Standard and Plus (104NT and PT1000)

High-speed CoreXY and Voron builders face bottlenecks with standard hotends that limit flow rate and heating efficiency, causing longer print times and inconsistent extrusion. Without a high-flow hotend like the Rapido 2, users risk under-extrusion and poor layer adhesion on demanding prints.

The Phaetus Rapido 2 Hotend is engineered for high-performance 3D printer builds such as Voron 2.4, Trident, and other CoreXY systems requiring ultra-high flow rates up to 75mm³/s. Featuring a planar ceramic heating element and a titanium heat break, this hotend delivers rapid heat-up times and superior thermal insulation. Its compatibility with V6 and Volcano nozzles, plus a detachable groovemount adapter, makes it a versatile upgrade for users seeking faster, more reliable extrusion with materials ranging from PLA to abrasive composites.

Why Upgrade?

• Achieve higher melt rates for faster print speeds on Voron 2.4 and Trident CoreXY printers
• Reduce risk of heat break deformation and clogging with titanium heat break and optimized inlet design
• Benefit from rapid heat-up times thanks to the planar ceramic heating element
• Maintain extrusion accuracy while increasing flow rate compared to Volcano hotends
• Enable printing of abrasive and composite filaments with hardened steel nozzle options

Best For:

• Voron 2.4 and Trident builders upgrading to ultra-high flow hotends
• CoreXY enthusiasts seeking reliable high-speed extrusion
• Users replacing Volcano hotends with a compact, high-performance alternative
• Filament users printing abrasive materials requiring hardened nozzles
• Klipper firmware users optimizing thermal management and print speed

Pair With the Right Filament

The Rapido 2 hotend’s high flow capacity and thermal stability make it ideal for advanced filaments that demand consistent extrusion.

• Carbon Fiber Filament — handle abrasive composites with hardened steel nozzles
• ABS Filament — benefit from stable high-temperature extrusion
• Nylon Filament — achieve reliable flow for engineering-grade materials
