Product Description

The original QIDI Max4 Tungsten Carbide Bimetal Nozzle 0.4 mm is a highly durable bimetal nozzle with a tungsten carbide tip, designed exclusively for the QIDI Max4 3D printer. It combines excellent thermal conductivity with extraordinary hardness and abrasion resistance, maintaining its nozzle diameter even after hundreds of hours of printing demanding composite filaments.

This nozzle is ideal for users utilizing filled materials (e.g., PLA-CF, PETG-CF, PA-CF, PA-GF, PC-CF etc.) and printing at the high speeds that the QIDI Max4 enables. The bimetal construction ensures fast heating and stable temperature, contributing to smooth material extrusion and better print surface quality.

Compatibility: only for the QIDI Max4 printer (not compatible with other QIDI models or standard V6 or MK8 nozzles).

Key Features

• Original QIDI accessory for Max4 – perfect fit and reliability.
• Tungsten carbide tip – extreme hardness and minimal wear even when printing abrasive filaments.
• Bimetal construction – optimized heat transfer, stable temperature profile, and reduced heat creep.
• 0.4 mm nozzle diameter – universal size for detailed and fast printing.
• High-temperature resistance – designed for hotend temperatures up to approx. 370 °C (per QIDI Max4 specifications).
• Compatible with Max4 high-flow hotend – suitable for fast printing with flow rates up to tens of mm³/s.
• Consistent print quality – precise nozzle diameter and smooth internal surface for consistent filament flow.
• Simple replacement – adapted for the Max4 modular hotend for quick maintenance.

Benefits for Users

• Longer lifespan than standard steel and hardened nozzles – ideal for intensive operation and production.
• Higher dimensional stability of parts because the nozzle diameter does not change over time.
• Less frequent nozzle replacement → less printer downtime and lower maintenance costs.
• Better print surface with composite and filled filaments that quickly wear down standard nozzles.

Recommended Use

This nozzle is particularly suitable for:

• Composite filaments with fibers – PLA-CF, PETG-CF, ABS-GF, ASA-CF, PA-CF/GF, PAHT-CF etc.
• Technical and high-strength materials – PC blends, engineering nylons, reinforcing materials.
• Long serial orders and industrial/semi-professional use where printing occurs many hours a day.

For non-abrasive filaments (PLA, PETG, ABS without filler), it will also provide very stable results, but the main benefit is appreciated with abrasive materials.

Technical Specifications

Warning: For safe nozzle replacement, always heat the hotend to operating temperature and follow the printer manufacturer's instructions.
