  • Optimized for 1.75mm filament;
  • Compatible with 2.85mm filament.
  • Requires a 8mm wrench

Main Advantages

  • Higher melt capacity
  • Affordable price
  • Machined with ultra-precision
  • Brass nozzle with Nickel coated surface
  • Follows the MK8 standard (M6×1 thread)
  • May be used with 1.75 or 2.85mm hotends.

Advantages of the Bondtech CHT™ technology:
Bondtech CHT™ nozzles split the filament into 3 thinner strands allowing to melt the material from within. In doing so, the material melts faster and higher flow rates can be used.

Advantages of the Nickel Coating

A Nickel coating is applied to our Coated Brass nozzles to provide protection against corrosion, erosion, and abrasion. Nickel coated nozzles have more corrosion resistance and lower coefficient of friction, which allows slicker feeding of material and delays plastic adhesion to the nozzle's surface.

Recommended Materials
Use this nozzle with the following materials:

  • PLA
  • ABS
  • HIPS
  • PC
  • TPU
  • TPE
  • Nylon
  • PETG
  • ASA
  • PP
  • PVA
  • For technical and abrasive materials we recommend to use other nozzles in our range.

Different nozzle sets for different materials
We recommend you to have several sets of nozzles because:
Using different materials with the same nozzles causes deposit build-up inside the nozzle.
These deposits will cause blockages.
We recommend changing nozzles when changing materials.

Impressive but...

I picked up the 0.6mm and the 0.4mm. I've yet to use the 0.4 nozzle but have a some time with the 0.6mm. Let me start off with... this thing can push filament hard. I was at 150mm/s@26mm3 flow rate and it didn't care. Went down smooth and at a surprising lower temp then I assumed. I did have to adjust my different flow/widths in the slicer as the defaults didn't work well but after some fine turning I got great results with PLA. Now for the not so great... I switched to PETG and it was terrible. It took a lot of fine tuning of speed for various types of layers and I'm still trying to work out retractions as it behaves quite differently than a brass nozzle. If you print mainly in PLA you'll enjoy this as an alternative to a volcano so you can bump those speeds and not worry but PETG seems to be a bit of a battle.
