The Bondtech CHT BiMetal nozzles were developed to provide the 3D printing industry with a sturdy and reliable nozzle for the faster 3D printing of abrasive materials such as composite filaments. The CHT BiMetal nozzles open a world of new opportunities for exploration and innovation, with cost-efficiency and versatility in mind. The CHT BiMetal nozzles are available in the following variants: V6 (RepRap M6) - M6 × 1 × 7.5 × 12.5, MK8 - M6 × 1 × 5 × 13, Volcano - M6 × 1 × 14.5 × 21.
With the CHT BiMetal nozzles, the users of V6, MK8 and Volcano hotends can now increase the flow rate by 25-65 % (depending on the hardware, materials and print settings used) and produce stronger parts for a wide variety of applications, with significant time gains. They 5 key advantages offered by the CHT BiMetal nozzles are:

All these properties are a result of the unique design of the CHT BiMetal nozzles in combination with the Bondtech CHT technology.
Standard abrasion-resistant nozzles are made using costly hard metals or crystal tips. This does indeed improve the nozzles abrasion resistance but it implies much higher manufacturing costs and slightly worse thermal efficiency (in the case of traditional hardened steel). Bondtech has solved this conundrum by designing the CHT BiMetal nozzles in three parts:
This design guarantees unmatched efficiency, ruggedness, and affordability. The CHT BiMetal nozzles are made up of copper with hardened vanadium steel inserts, all coated with a nickel coating. These materials have the following benefits:
Another reason why the CHT BiMetal nozzles perform so well is the Bondtech CHT technology.
The Core Heating Technology (CHT) ensures higher melt capacity of the nozzle by increasing the surface area of the heating walls. Bondtech CHT Nozzles split the filament into 3 thinner strands (visible in Image 3) allowing the material to melt from within. This makes the material melt faster and allows the use of higher flow rates.
This phenomenon is very well explained and demonstrated in the video. The results of a printing competition are shown where the only difference is the nozzle used - CHT vs. standard. While all the other printing parameters and material stay the same, the CHT nozzle produces a perfect part after increasing the flow rate gradually from 17 to 26 mm3/s, while the standard nozzle starts to produce a defective part already at 20 mm3/s.
There are a few things that must be kept in mind at the time of installing and using the CHT BiMetal nozzles to ensure their maximum performance and longevity.
Firstly, since copper is a soft material and doesn't withstand high mechanical efforts, it is recommended to heat up the nozzle to 280 °C (at least above 250 °C) before removing or tightening it. For that purpose, a torque of 0.5 Nm is recommended (at most 1.0 Nm).
Furthermore, the 0.4 mm diameter nozzles should not be used with carbon or glass fiber reinforced filaments (best to use the other diameters), and as far as metal, wood, glitter, or other particle-loaded abrasive filaments, all diameters can be used.
Bondtech nozzles with CHT BiMetal technology are optimised for 1.75 mm filament, ensuring optimum quality with filament of this diameter. However, these nozzles are also compatible with 2.85 mm diameter filament.
The following manufacturer's recommendations should be followed when changing the nozzle:
It is also crucial to use the right tools (6 mm wrench) and level the printer base once the new nozzle is installed.
