Snapmaker and Phaetus have introduced a jointly developed hotend for the Snapmaker U1 FFF printer.
Combining 'high volumetric flow' with 'enhanced wear resistance and precision engineering,' the new Snapmaker × Phaetus Liber hotend is said to be ideal for batch production and rapid prototyping.
Designed specifically for the U1, the hotend integrates Phaetus’ Liber Split-Flow Melt Channel, a DLC-coated hardened-steel nozzle, and a precision-machined seamless heat break into one hotend assembly.
Per the partners, volumetric flow determines how much molten material a hotend can deliver each second, and by dividing the melt path into optimised channels, the Liber Split-Flow Melt Channel increases the effective surface-to-volume ratio and helps heat reach the filament more effectively.
Under matched energy-use test conditions, volumetric flow of the high-flow hotend is said to have 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, Snapmaker and Phaetus say, where material delivery can become the primary limit on printing speed.
“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 specialised 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.”
“We are delighted to partner with Snapmaker on the Liber High Flow Hotend,” added 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.”
Among the benefits of the Snapmaker × Phaetus Liber hotend are a sustained high-flow extrusion capability that maintains higher volumetric flow across long perimeters, broad infill regions, and other continuous paths, and an efficient melting capability that maintains interlayer adhesion and fine surface quality. The two companies also say the nozzle combines a hardened-steel substrate rated at HV 725–780 with a wear-resistant DLC coating, helping to reduce material adhesion, leakage and clogging thanks to a seamless heat break with an internal surface roughness of Ra ≤ 0.2 μm, micron-level machining tolerances, and precision-mated end faces.
The Snapmaker × Phaetus Liber High Flow Hotend for U1 is priced at. around $34.99. The Snapmaker × Phaetus Liber High Flow Hotend Bundle for U1 includes four hotends and is priced at around $119.
