Snapmaker Liber™ High Flow Hotend Bundle by Phaetus, 0,4 mm (4 pieces)

The Phaetus Liber™ High Flow Hotend is a high-flow hotend developed specifically for the Snapmaker U1. With an optimised melt channel, a precision-machined titanium heat bridge and a hardened, DLC-coated steel nozzle, it increases volumetric flow by up to 87% compared with the U1's standard stainless-steel hotend, while maintaining the same power consumption.

Split-channel melt structure for higher throughput

The Liber™ hotend uses a split-channel structure in the melt zone to optimise the filament path and reduce heat loss. Compared with the standard hotend, volumetric flow increases by up to 87% with ABS, 66% with PLA and 43% with PETG HF.

Hardened steel with DLC coating

The nozzle is made from hardened steel with an additional DLC coating, giving it a surface hardness of around HV 2000, while the base material itself measures approximately HV 725–780. By comparison, the U1's standard stainless-steel nozzle is rated at around HV 170–210. This makes the Liber hotend significantly more resistant to wear from abrasive filaments.

Precision-machined heat bridge to reduce clogging

The titanium-alloy heat bridge is precision-machined and has an internal channel roughness of Ra ≤ 0.2 µm. Smoother inner walls reduce filament adhesion and residue build-up, helping to ensure more consistent and reliable filament flow. Micrometre-level manufacturing tolerances also provide precise component interfaces and minimise the risk of material leakage at the joints.

Reliable quality even at high speeds

Compared with other high-flow hotends, the Liber™ hotend delivers reduced stringing, cleaner overhangs and bridges, and more consistent surface quality, even at high print speeds.

► Filament compatibility

The Liber hotend is compatible with a wide range of filaments, including standard and effect PLA grades, PETG (including HF and Translucent), ABS, ASA, PC, as well as carbon- and glass fibre-reinforced materials such as PLA-CF, ASA-CF, PA6-CF/GF and PAHT-CF. When switching from filaments with print temperatures above 250 °C to more temperature-sensitive materials such as PLA or PETG, the heat bridge must be cleaned. Carbon- and glass fibre-reinforced filaments, as well as wood-filled PLA and TPU, are compatible but are not specifically recommended due to the potential risk of clogging or inconsistent feeding.
