Overview

The Micro Swiss FlowTech DiamondBack 0.4mm nozzle features a proprietary polycrystalline diamond insert for increased wear resistance when printing abrasive carbon-embedded filaments. Its durable tip helps reduce clogging and support precise prints with strong layer adhesion, while letting you switch between standard PLA and abrasive materials without changing nozzles.

What the FlowTech DiamondBack nozzle does

The Micro Swiss FlowTech DiamondBack Nozzle is a 0.4mm performance nozzle built for the FlowTech ecosystem and designed for demanding 3D printing materials. Developed through a collaboration between Micro Swiss and DiamondBack, the nozzle uses a proprietary Polycrystalline Diamond (PCD) insert to improve durability, print precision, and reliability in challenging applications.

The DiamondBack design is intended to handle a wide material range, from everyday PLA to abrasive carbon-embedded filaments, without requiring a nozzle change. That makes the nozzle a practical option for users who want one setup for both standard and wear-intensive printing.

Key features of the Micro Swiss and DiamondBack collaboration

Proprietary Polycrystalline Diamond insert

The nozzle features a proprietary PCD insert developed after 40 years of diamond technology research. This construction is aimed at the most challenging printing applications where conventional nozzle materials wear more quickly.

Solid diamond tip for durability and cleaner extrusion

A solid diamond tip provides high durability while also helping reduce clogging. The same construction supports stronger layer adhesion and better print precision across a broad range of materials.

One nozzle for standard and abrasive filaments

The FlowTech DiamondBack nozzle is designed to print with any filament, including standard PLA and abrasive carbon-embedded filaments. Users can move between material types without switching to a different nozzle.

Extended service life

The diamond insert delivers strong wear resistance and thermal conductivity. Compared with traditional nozzle materials, that combination is intended to significantly increase nozzle lifespan.

Made in USA

The Micro Swiss FlowTech DiamondBack nozzle is manufactured in the USA.

Where a 0.4mm DiamondBack nozzle fits best

•

Everyday printing with PLA: Suitable for regular production and general-purpose parts while maintaining the convenience of a standard 0.4mm nozzle size.

•

Abrasive filament printing: Well suited to carbon-embedded materials that can rapidly wear conventional nozzles.

•

Mixed-material workflows: Useful for makers, engineers, and small production environments that switch between standard and abrasive filaments.

•

Precision-focused prints: Built to support reduced clogging, improved layer adhesion, and consistent print quality in demanding jobs.
