Phaetus Rapido Plus Hotend 2 UHF

Product Description

Phaetus Rapido Plus Hotend 2 UHF is a revolutionary high-flow thermal extrusion system engineered for industrial-grade performance, lightning-fast printing speeds, and extreme reliability. This 2nd-generation Ultra High Flow (UHF) variant features an optimized, elongated melt zone architecture designed to maximize volumetric flow rates, allowing high-speed CoreXY machines to run at peak capacity without facing under-extrusion bottlenecks. Built with a heavy-duty cylindrical ceramic heating core, it provides uniform 360-degree thermal distribution and rapid heat-up times, ensuring consistent plastic melting even during high-throughput demands.

The “Plus” variant of this hotend integrates an advanced Pt1000 RTD temperature sensor directly into its heated core matrix. This high-accuracy sensor allows for precise thermal tracking up to 350°C (and configurable up to 500°C with specialized firmware setups), making it fully compatible with engineering-grade materials like carbon fiber-infused ABS, ASA, Nylon, and Polycarbonate. The redesigned structural titanium alloy throat block provides incredible rigid support, enabling one-handed nozzle changes while ensuring a reliable, leak-free mechanical seal that eliminates filament oozing at high pressures.

For dedicated makers operating custom motion platforms like the Voron Trident, the Phaetus Rapido Plus Hotend 2 UHF represents the ultimate toolhead upgrade. Its lightweight, compact frame reduces gantry weight, effectively minimizing inertia, ringing, and ghosting during fast accelerations. Delivered as a complete kit containing specialized high-flow copper alloy nozzles and modular mounting components, this hotend is the premier choice for professional print farms and technical manufacturing environments.
