Up to 87% higher volumetric flow with PLA, ABS, and PETG HF for batch production and rapid prototyping
SHENZHEN, China, Sept. 22, 2026. Snapmaker and Phaetus today announced the Snapmaker × Phaetus Liber™ High Flow Hotend for U1, jointly developed for Snapmaker U1. Combining high volumetric flow with enhanced wear resistance and precision engineering, the new hotend is ideal for batch production and rapid prototyping.
“U1 continues to grow with its users,” said Mickey Ke, Chief Operating Officer at Snapmaker. “The growth of its accessory ecosystem is central to that vision. By combining Snapmaker’s platform engineering with the specialized expertise of partners such as Phaetus, we can respond to a wider range of user needs and continue adding value throughout the product’s lifecycle. This collaborative approach also reinforces what the Snapmaker brand stands for: products that remain adaptable, capable, and closely connected to real-world creative workflows. The Liber High Flow Hotend is an important step in building that ecosystem and lays the groundwork for further collaboration around U1.”
What is the Liber™ High Flow Hotend for U1?
The Liber High Flow Hotend is a complete U1-specific extrusion module. It integrates Phaetus’ Liber Split-Flow Melt Channel, a DLC-coated hardened-steel nozzle, and a precision-machined seamless heat break into one hotend assembly designed around the U1 hardware architecture and printing workflow.

Up to 87% higher volumetric flow
Volumetric flow determines how much molten material a hotend can deliver per second. The Liber Split-Flow Melt Channel divides the melt path into optimized channels, increasing the effective surface-to-volume ratio and helping heat reach the filament core more efficiently.
Under matched energy-use test conditions, volumetric flow of the high flow hotend increased by 66% with PLA, 87% with ABS, and 43% with PETG HF compared with the U1 Stainless Steel Hotend. The higher sustained output is particularly valuable for large-volume models and long, continuous extrusion paths, where material delivery can become the primary limit on printing speed.
“We are delighted to partner with Snapmaker on the Liber High Flow Hotend,” said Donald Wan, Chief Technology Officer at Phaetus. “Snapmaker’s rigorous engineering and focus on user experience complement Phaetus’ extrusion expertise. Working closely, our teams combined high melt-flow performance, precise control, durability, and ease of use in a solution developed for U1. This collaboration is an important step toward a more open technology ecosystem, and we look forward to working with Snapmaker to advance 3D printing innovation and adoption.”

Designed for productive, dependable printing
- Greater efficiency on large prints: Sustained high-flow extrusion helps U1 maintain higher volumetric flow rate across long perimeters, broad infill regions, and other continuous paths, reducing slowdowns caused by limited melting capacity.
- Consistent high-speed quality: Efficient melting and stable extrusion help maintain interlayer adhesion and fine surface quality. Comparative testing also showed reduced stringing and oozing.

Expanding the U1 Partner Ecosystem
The launch represents an important step in the development of the U1 partner ecosystem. By introducing professionally engineered components from specialist technology partners, Snapmaker can address a wider range of printing requirements while maintaining an integrated U1 experience. The collaboration also reinforces U1 as an evolving platform that can expand with new materials, applications, and user needs.
