Anycubic Brass Nozzle for Kobra 3 Max

The Anycubic Brass Nozzle for Kobra 3 Max is an original replacement 0.4mm nozzle designed for the Anycubic Kobra 3 Max hotend.

The 0.4mm diameter provides a practical balance between print detail, extrusion flow, printing speed, and general-purpose usability. Brass offers excellent thermal conductivity, allowing heat to transfer efficiently into the filament for smooth and consistent extrusion.

It is an ideal replacement for a worn, damaged, or blocked original nozzle and is particularly well suited to standard non-abrasive materials such as PLA, PETG, ABS, and TPU.

Key Features

• Original Anycubic replacement nozzle

• Designed for Anycubic Kobra 3 Max

• Standard 0.4mm nozzle diameter

• Brass construction for efficient heat transfer

• Suitable for general-purpose FDM printing

• Supports detailed printing while maintaining good material flow

• Ideal for common non-abrasive 1.75mm filaments

• Direct replacement for a worn or damaged original nozzle

Standard 0.4mm Nozzle Diameter

The 0.4mm nozzle is the standard nozzle size used by the Kobra 3 Max.

It provides a balanced combination of:

• Print detail

• Layer height flexibility

• Printing speed

• Material flow

• Surface quality

• General-purpose reliability

This makes it suitable for most everyday printing applications without requiring specialized slicer configurations.

Brass Construction

Brass is widely used for 3D printer nozzles because of its excellent thermal conductivity.

Efficient heat transfer helps the filament melt consistently as it passes through the hotend, supporting smooth extrusion and stable material flow.

Brass nozzles are particularly suitable for non-abrasive materials including:

• PLA

• PLA+

• PETG

• ABS

• ASA

• TPU

• Other compatible standard filaments

Good for Fine Detail and General Printing

A 0.4mm nozzle provides enough resolution for detailed models while still allowing practical printing speeds.

It is suitable for:

• Functional prototypes

• Figurines

• Decorative models

• Large-format prints

• Household parts

• Organizers

• Educational models

• Product prototypes

• General-purpose printing

Designed for the Kobra 3 Max

This nozzle is specifically listed by Anycubic for the original Kobra 3 Max platform.

The Kobra 3 Max uses 1.75mm filament and is supplied with a standard 0.4mm nozzle configuration.

For replacement, use the nozzle version intended for the original Kobra 3 Max rather than assuming newer Kobra 3 Max V2 components are interchangeable.

Not the Same as Kobra 3 Max V2 Nozzle

Anycubic specifically states that the Kobra 3 Max V2 nozzle / printhead configuration is not compatible with the original Kobra 3 Max.

When ordering a replacement nozzle, confirm whether the printer is:

• Kobra 3 Max

• Kobra 3 Max Combo

• Kobra 3 Max V2

• Kobra 3 Max V2 Combo

This product is intended for the original Kobra 3 Max / Kobra 3 Max Combo.

When to Replace a Nozzle

A nozzle is a consumable component and gradually wears during use.

Replacement may be required if you notice:

• Inconsistent extrusion

• Reduced print quality

• Persistent partial clogging

• Irregular extrusion width

• Damaged nozzle tip

• Excessive filament buildup

• Dimensional changes around the nozzle opening

• Poor first-layer consistency despite correct calibration

Replacing a worn nozzle can restore more consistent material flow and print quality.

Technical Specifications

Applications

• Standard FDM printing

• PLA printing

• PETG printing

• ABS printing

• TPU printing

• Functional prototypes

• Decorative models

• Large-format prints

• Replacement of worn nozzle

• Hotend maintenance

• Print farm spare-part inventory

Compatibility

Compatible with:

• Anycubic Kobra 3 Max

• Anycubic Kobra 3 Max Combo

Not Compatible With

Do not assume compatibility with:

• Anycubic Kobra 3 Max V2

• Kobra X

• Kobra 4

• Kobra S1 Max

• Kobra S1

• Other Anycubic models using different hotend systems

Brass Nozzle and Abrasive Filaments

Brass provides excellent thermal conductivity but is softer than hardened-steel nozzle materials.

For frequent printing with abrasive filaments such as:

• Carbon-fiber-filled filament

• Glass-fiber-filled filament

• Highly abrasive composite filament

a compatible hardened or wear-resistant nozzle is generally a better choice.

Using abrasive filament continuously through brass can enlarge the nozzle opening over time and affect extrusion accuracy.

Package Includes

• 1 × Anycubic Brass Nozzle for Kobra 3 Max – 0.4mm

Replacement Note

Allow the hotend to cool before beginning service, and follow the correct Anycubic nozzle replacement procedure.

After installing a replacement nozzle:

• Confirm that it is correctly seated

• Check for filament leakage

• Verify nozzle size in the slicer

• Run the required printer calibration

• Check the first layer before starting a long print

Do not overtighten the nozzle, as excessive force can damage the hotend or threads.

Product Revision Note

Anycubic notes that Kobra 3 Max nozzle assemblies may be supplied in different production revisions.

Appearance or material details may therefore vary slightly between batches while maintaining normal compatibility and function.

Always match the replacement to the original Kobra 3 Max platform rather than the newer Kobra 3 Max V2.
