Nozzles for 3D printers made of metal with at least one or a multitude of holes to increase the standard circular surface area of the heating walls.

30% gains or more!!?? Check the White Paper:

"Increasing Melt Capacity With 3 Nozzle Features"

Gains apply to 1.75 / 2.85mm rigid materials and 2.85mm flexible filaments only.

To achieve meaningful volumetric flow gains use at least 0.6mm diameter nozzles.

Main Bondtech CHT ® Advantages
  • Higher melt capacity by increasing the surface area of the heating walls
  • Affordable price
  • Machined with ultra-precision
  • Brass nozzle with Nickel coated surface
  • Follows nozzle standards:
    • RepRap (M6×1×7.5×12.5)
    • MK8 (M6×1×5×13)
    • Volcano (M6×1×14.5×21)
  • 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.


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.

1 review for Bondtech CHT ® M6 Coated Brass Nozzle

  1. Detlev Rackow (verified owner)

    Nice improvement, even with a high-flow hotend.

    I compared my current plated copper 0.4mm nozzle to the new Bondtech CHT nozzle. The chinese plated copper nozzle has seen a few spools of use and was cleaned with two coldpulls with both ABS and Nylon. Nothing bad came out.

    All tests were done at 243° with Esun ABS+, no parts cooling fan, extruding into free air. The Orbiter was set to 0.7A RMS, I run a chinese hotend with a bi-metallic high flow heatbreak.

    243° is what I use for regularly printing ABS+. I could have gotten higher numbers at higher temperatures, but this is what I use to do actual prints. Go higher and the pring quality will suffer as the extrusion will look melty on overhangs or on slow layers.

    The extrusion speed was set in Fluidd, for each speed I made a test-extrusion of 270mm. This is more than any printer can do in a straight line without slowing down. It’s a test to find the limits.

    I noted the speed, at which I heard the first click from the extruder over the long extrusion.

    The chinese copper nozzle would allow 10.5mm/s without clicks, at 10.6 came a single click. This turns out as 25.26mm³/s “continuous” extrusion without a single click.

    The Bondtech CHT nozzle would allow 12.1mm/s and give me a click at 12.2mm/s. This turns out as 29.1mm³/s.

    25.25 vs 29.1mm³/s. This is nice, it is actually more than I expected, given that I already used a high-flow hotend with a long meltzone.

    These are not real life numbers. You can allow more flow in your slicer, as you can never extrude 290mm of filament in any single direction – the printer has to slow down and accelerate again at turns.
    Is it a good nozzle? Definitely yes.

    Should one make the switch? I think it depends. If you need to push out bulk parts in good quality, it’s a very good solution that pays for itself.
