Snapmaker × Phaetus® Liber™ High Flow Hotend for U1
About this item
Product Feature
Up to 87% Higher Volumetric Flow
Liber™ split-flow technology optimizes the melt path for faster, more efficient extrusion without increasing energy consumption.
Up to 51.98% Faster Printing
High-flow performance significantly reduces printing time on large, continuous-extrusion models. In the listed test, printing time dropped from 7h 59min to 3h 50min.
DLC-Coated Hardened Steel Nozzle
Hardened steel with DLC coating improves surface hardness and wear resistance, helping extend nozzle life during demanding printing.
Ultra-Smooth, Clog-Resistant Filament Path
A precision-machined seamless heat break with Ra ≤ 0.2 μm inner-surface roughness reduces filament adhesion, residue, leakage, and clogging.
Reliable Print Quality at High Speed
Efficient melting and consistent extrusion help maintain interlayer adhesion, fine surface details, bridging performance, and overall print quality even at higher speeds.
Authencity Guaranteed
We only sell authentic products from verified brand partners and retail partners globally.

Important Notes
- The High Flow Hotend is best suited for printing large models with long, continuous extrusion paths, where its high-speed, high-flow capabilities can be fully utilized. For models with intricate details, complex curved surfaces, numerous corners, or frequent changes in direction, printing speeds may be limited, and the benefits of the High Flow Hotend may be less noticeable.
- The U1 currently does not support using hotends with different nozzle diameters in the same print job. Before printing, ensure that all toolheads used in the print job are equipped with hotends of the same nozzle diameter.
- For hotend installation instructions, refer to the U1 Hotend User Guide.
- When switching from high-temperature filaments, such as ABS, ASA, PA, or PC, to heat-sensitive filaments, such as PLA or PETG, perform a cold pull before printing to help prevent clogging. Use the printer's unloading procedure to unload the high-temperature filament, then load the new filament without starting the loading procedure. Set the nozzle to the high-temperature filament's printing temperature and manually extrude until the residual filament is fully purged and the new filament flows smoothly. Lower the nozzle temperature to 220-240°C and continue extruding as it cools. Then lower it to 85°C and, once cooled, slowly pull the filament upward. A three-pronged tip indicates a successful cold pull. If the filament cannot be extruded, increase the nozzle temperature or clear the nozzle with a cleaning needle. For more details, refer to the U1 Hotend User Guide on the official Wiki.
