Description
Push high-speed 3D printing further with the Phaetus Rapido X, a next-generation high-flow hotend built for extreme extrusion performance, engineering materials, and demanding DIY printer builds.
At the heart of the Rapido X is Phaetus's Liber™ High-Flow Module, designed to increase the filament's contact area with the melt zone for faster, more consistent melting. The result is a hotend capable of reaching up to 103 mm³/s maximum flow, with Phaetus specifying up to 65 mm³/s stable extrusion for sustained high-speed printing.
A powerful 24V 120W ceramic heater provides rapid heat-up performance, reaching approximately 200°C in 25 seconds and 300°C in 45 seconds. With a maximum operating temperature of 360°C, the Rapido X is equally at home printing everyday materials like PLA, PETG, ABS, and TPU or demanding engineering filaments including nylon, PC, PA-CF/GF, PEI, and PEEK.
Liber was developed by Phaetus and is manufactured by Runice Co., Ltd. It carries the FlowCore mark, which identifies products manufactured under license to the patents published at flowcoreip.com. Liber and FlowCore are registered trademarks.
Built for Serious Flow
The Rapido X's redesigned melt path and Liber™ technology improve thermal transfer into the filament, allowing significantly more material to be melted without simply making the hotend excessively long. Phaetus rates the Rapido X for printing speeds of up to 1300 mm/s, provided the rest of the printer is capable of supporting those speeds.
Its optimized thermal isolation and cooling architecture also help reduce heat creep during sustained high-flow printing, maintaining a more defined separation between the hot and cold zones.
EndCoat® Gen 2 Wear-Resistant Nozzles
Rapido X includes Phaetus's EndCoat® Gen 2 coated hardened-steel nozzles, designed for improved wear resistance when printing abrasive materials such as carbon-fiber and glass-fiber composites.
The hotend uses a standard M6 / V6-style nozzle interface, giving builders considerably more flexibility when choosing replacement or specialty nozzles. Rapido X includes both 0.4 mm and 0.5 mm EndCoat nozzles.
Designed for DIY Printers
Rapido X is designed with custom printers and high-performance DIY machines in mind, featuring multiple mounting points and a detachable nozzle interface for easier integration.
Important: Rapido X uses a new mounting design and is not directly mounting-compatible with previous Rapido or Rapido 2 hotends. Builders upgrading an existing machine should verify their toolhead or mount supports the Rapido X before ordering.
