Keep your QIDI MAX4 printing like it should with genuineQIDI OEM hardened steel bimetal nozzles.

Designed specifically for the QIDI MAX4 hotend, these replacement nozzles combine the durability of hardened steel with the improved thermal performance of a bimetal construction. That means dependable extrusion, efficient heat transfer, and better resistance to wear when printing abrasive materials such as carbon-fiber, glass-fiber, glow-in-the-dark, and wood-filled filaments.

Because these are genuine QIDI components, you get the proper fit and geometry for your MAX4no questionable adapters, mystery tolerances, or hoping that an almost-compatible nozzle is compatible enough.

Built for Abrasive Filaments

Standard brass nozzles can wear surprisingly quickly when exposed to reinforced or filled materials. The hardened steel filament path provides greater wear resistance, helping the nozzle maintain its intended diameter and extrusion performance over longer periods of use.

They are an excellent choice for printing:

• Carbon-fiber-reinforced filament

• Glass-fiber-reinforced filament

• Glow-in-the-dark filament

• Wood-filled filament

• Metal-filled filament

• Engineering and composite materials

• Standard PLA, PETG, ABS, ASA, and other everyday filaments

Integrated Nozzle and Throat Design

The nozzle and throat are combined into a single all-metal assembly for quick removal and straightforward replacement. The integrated design eliminates an additional threaded connection in the melt zone and ensures the replacement assembly matches the original QIDI MAX4 hotend configuration.

Less fiddling, fewer opportunities for installation errors, and more time spent actually printing.

Choose the Right Nozzle Size

0.2mm Maximum Detail
Ideal for small features, miniature models, fine lettering, and parts where surface detail matters more than speed. Best suited to standard, unfilled filaments.

0.4mm Everyday Versatility
The dependable all-around choice for a balance of detail, print speed, and material compatibility.

0.6mm Faster, Stronger Prints
A great option for functional parts, larger layer heights, increased material flow, and fiber-filled filaments that may be more prone to clogging in smaller nozzles.

0.8mm Maximum Output
Built for large models, thick walls, rapid prototyping, and parts where strength and production speed matter more than tiny details.

Compatibility

• QIDI MAX4

These nozzles are designed for the MAX4 hotend and should not be assumed to fit other QIDI printers. QIDI uses different nozzle lengths and hotend designs across several printer models, even when the parts look suspiciously similar.

Whats Included

• 2 QIDI MAX4 hardened steel bimetal nozzles in the selected diameter

Important Filament Note

QIDI recommends dedicating each nozzle to filaments with similar printing-temperature ranges. Frequently switching a single nozzle between materials with substantially different processing temperatures may leave residue in the melt path and increase the likelihood of a clog.

For example, keeping one nozzle for lower-temperature materials and another for high-temperature engineering filaments can make material changes easier and more reliable.
