Bondtech CHT ® Nozzles

For non abrasive materials

1.75mm Nozzles compatible with 2.85mm filament

From their release the Bondtech CHT ® nozzles became the best upgrade kit a printer could have. A simple addition of a nozzle provided at least 33% volumetric flow gains. Depending on material, nozzle temperature and nozzle size, the gains could rise to over 60% in flow.

Remember that as demonstrated in our White Paper, these gains have meaningful expression at nozzle diameters of 0.6mm and above.

These nozzles support all non abrasive materials. Available standards are M6 (RepRap), MK8, VOL (Volcano) and CSP (C.SPider).

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.

Main Bondtech CHT ® Advantages
  • Higher melt capacity by increasing the surface area of the heating walls
  • Affordable price
  • Machined with ultra-precision
  • Brass nozzles with Nickel coated surface
  • Follow nozzle standards:
    • M6 [RepRap] [MOS] (M6×1×7.5×12.5)
    • MK8 (M6×1×5×13)
    • VOL [Volcano] (M6×1×14.5×21)
    • CSP [Creality SPider] (M6×1×9×16.8)
  • 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.
