Consistent extrusion

I've noticed much more consistent extrusion rates since installing this nozzle. There are fewer clogs when switching between different materials, and the layer adhesion looks fantastic.

Great quality, slightly tricky install

The print quality is excellent and the heat distribution seems very even. Installation took a bit longer than expected because I had to ensure the hotend was at the exact right temperature to avoid stripping threads, but once on, it works flawlessly.

Perfect upgrade for abrasive filaments

I switched to this bi-metal nozzle specifically for printing carbon fiber PLA, and it has held up perfectly. My old brass nozzle wore out in two prints, but this one shows no signs of wear after several spools.

Essential for the Plus 4

If you own a QIDI Plus 4, this is a must-have accessory. The bi-metal construction offers the best of both worlds: the thermal conductivity of copper and the durability of steel. Highly recommended.

Good value for money

Solid build quality. It's not as cheap as a standard brass nozzle, but considering how long it lasts with abrasive materials, it pays for itself quickly. Deducting one star only because shipping took a few days longer than estimated.

No more clogging issues

I was constantly battling clogs with my previous setup. Since installing the QIDI bi-metal nozzle, my prints have been smooth and uninterrupted. The internal surface finish seems very polished.

5 FAQ

Q: Does this come in different sizes like 0.2mm or 0.6mm?

A: Currently, this specific listing is for the 0.4mm diameter nozzle, which is the standard size for most applications. We do offer other sizes in separate listings; please check our store catalog for 0.2mm, 0.6mm, and 0.8mm options compatible with the Plus 4.

Q: Can I use this nozzle to print pure metal filaments?

A: No, this nozzle is designed for standard thermoplastics and composite filaments (like those filled with carbon fiber or glass). It is not suitable for printing pure metal filaments that require sintering or extremely high temperatures beyond 300°C.

Q: How does the lifespan compare to a hardened steel nozzle?

A: The bi-metal design offers a lifespan comparable to full hardened steel nozzles when printing abrasive materials, but often provides better thermal stability and faster heat transfer due to the copper core, leading to improved print quality.

Q: Is this nozzle compatible with the original QIDI Plus model?

A: This specific bi-metal nozzle is designed exclusively for the QIDI Plus 4. While the thread size may be similar, we recommend checking your specific hotend assembly dimensions before purchasing for older models to ensure proper fitment.

Q: What is the recommended temperature for tightening the nozzle?

A: For optimal installation, please heat the hotend to approximately 250°C. This ensures the thermal expansion allows for proper seating without damaging the threads. Always use the provided wrench and avoid over-tightening.
