HRA 90 Tougher Nozzle, Lower Maintenance

With HRA 90 hardness compared to hardened steel’s 74, the tungsten carbide nozzle provides exceptional wear resistance.
This results in a 50% increase in lifespan when printing abrasive, high-performance fiber-reinforced filaments.

Quick Swap Nozzle Design

The special design of the hotend heating assembly enables easy separation of thermal and electronic components.
Simply unlock the latch for quick and easy hotend removal and installation.
Please ensure the hotend has cooled down before swapping and avoid touching the heat block to prevent burns.

0.2mm Nozzle – Optimal Print Fineness


The smaller nozzle diameter extrudes thinner filament lines, enabling higher detail resolution and finer surface quality, especially on horizontal print surfaces where precision and smoothness are critical.

0.6mm & 0.8mm Nozzle – Faster Print Speed


Larger nozzle diameters allow more filament to be extruded per second, significantly increasing print speed while maintaining stable flow, making them ideal for large parts, functional prints, and high-throughput production.

    1. If you need multi-color printing with the AMS, connect the AMS to the right-side Fixed Hotend.
    2. If you want to use the second hotend for support-material printing, we recommend using the Liftable Hotend.
    3. TPU85A is only supported on the right-side Fixed Hotend. TPU95AHF/90A is expected to be supported on the left-side Liftable Hotend starting from firmware version U2.
    4. PET-CF / PPA-CF / PPS-CF are supported only on the left-side Liftable Hotend.
