More info about the Bondtech CHT ® nozzles
After a long year of Product Development and researching 3DSolex’s Core Heating Technology, we have the Bondtech CHT ® high flow nozzles out.
Coated Brass first.
Get 30% more melt capacity from your hotend
It may sound like snake oil but it is in fact a leap forward. The Core Heating Technology is effective. The results are even better than what we promise on our Marketing.
We did a deep study and published the White Paper “Increasing Melt Capacity With 3 Key Nozzle Features”.
It shows the Bondtech CHT ® nozzles bring average gains on Volumetric Flow Rate performance above 60%.
Read White PaperThe video below shows a challenge between two 0.6 mm nozzles running on a Prusa MK3S with an LGX® Shortcut Copperhead™ Upgrade Kit and a Bondtech® 50W heater. To the left a Standard Coated Brass nozzle. To the right a Bondtech CHT ® nozzle.
A model is sliced to go through a speed and Flow Rate slow increase from 17 up to 26 mm^3/s. The same G-code is used on both print jobs.
Both nozzles work well up to 19 mm^3/s. Above that, performance differences are well visible. Which one will do a better job?
What About
Cold Pulls?
No problem with doing cold pulls or atomic pulls. This is how the strand comes out from the extruder side.

What About
Retractions?
No problem with retractions. Here is a skull printed with a 0.6mm nozzle using 0.6mm as retraction distance.
What About
Abrasive Materials?
Not compatible with abrasive materials. First version out is Nickel Coated Brass. We plan to have a harder versions later.

What About Copper nozzles?
We made some already. We are testing them.
We may come to have Copper Bondtech CHT ® nozzles in the Future.
Currently we are working on extending the nozzle range to cover the MK8 and Creality Pro standards.

Is it worth $19.90USD?
Absolutely!! It pays itself fast.
- After 30 hours printing you save at least 10
- Each machine-hour saved cost at most $1 . 99 USD
- The nozzle is then on for free

will you release for MK10?
Hi Tomas,
Bondtech CHT MK10 is not currently in our plans.
If there is demand pressure we will have to consider it though.
Do you use any of these printers:
Monoprice Maker Select, Wanhao Duplicator i3 (D4, D6), Qidi Tech, Cacoon Create, FlashForge Creator (Dreamer, Finder)?
I would also love to see a mk10 nozzle. i use the Qidi tech x-max and i fast. and x one 2 all use the mk 10 nozzle. I have the cht mk8 on my creality and hands down the cht is my absolute go to nozzle on that printer.
Hi Andrew,
We are considering adding MK10 versions.
We are not fully sure yet, as the market for that standard is actually very small.
We will have more news on this matter soon.
I’m interested in a CHT nozzle for my FlashForge Creator Pro (that has an all-metal hotend from Micro Swiss).
Hi,
We only use RepRap and MK8 standards on our CHT nozzles so far.
If the MicroSwiss all-metal for the FlashForge Creator Pro follows the MK10 standard, it isn’t compatible with the Bondtech CHT nozzles.
Thank you for sending us your comment.
hi, is this nozzle compatible with hotend paethus dragonfly? or is there any nozzle that is fine in your store?
Hi Vincenzo,
Yes, the Phaetus Dragonfly is compatible with both products at the bottom of this article.

Are there recommended print settings to start out with? I will be fiddling with retraction to reduce blobbing but I would like to know if there is anything else I should consider.
Hi Gavin,
The CHT nozzles allow you to increase the speed, widen the extrusion width, and/or increase layer thickness, as your hotend will have more melt capacity.
Other than that, no, not really. Same general settings may be used.
Is the CHT nozzle a good fit to use with Prusa MMU? I’m thinking it’s retraction might be an issue.
Hi MarkFrTX,
We’ve never had problems with short retractions using the CHT nozzles. That wouldn’t be an issue.
What could be perceived as an issue, and maybe it is what you are referring to, is the filament’s tip shape on long retracts and loads.
The CHT nozzle is not expected to have an impact on it.
We say this without having tested the CHT with a MMU though.
From the work we did with the MMU, we know the shape of the tip is formed within or above the solid-to-melt transition, but clearly above the nozzle.
For that reason we are lead to believe the tip sharpness will not depend on the nozzle’s channels shape.
What about ultimaker 2 olssom block? Is it compatible?
Hi Alain,
Yes, the Olssom block is RepRap compatible and the RepRap CHT nozzle can be used with 2.85mm filament.

Thank you.
The flats on the CHT nozzles appear to have the same thickness across all of the orifice diameters. This makes the less-gigantic ones much less adaptable than they could be.
Contrast the good old E3D Nozzle Fun Pack, whose 0.6 and 0.8 nozzles have flats which are bigger in proportion to their orifices, giving each of those nozzles a huge amount of flexibility as to the line-width.
Are there any plans to use wider flats on any of the CHT nozzles?
Hi,
Thank you for sending us your comment.
Each manufacturer has their own philosophy and we don’t want to comment on how anyone else did how they did.
The CHT nozzles have specific shoulders that in our opinion allow for very much flexibility.
By orifice size here is the diameter of the corresponding shoulder (or flats as you call it):
We have no plans to increase these shoulder diameters.
We may come to decrease them when creating specific standards for non-planar 3D printing.
hi! is this nozzle compatible with the “phaetus dragon” standard flow hotend?
thanks!
Hi Tiju,
Sorry for the delayed reply.
Yes, the Phaetus Dragon can use the Bondtech CHT nozzles, namely the RepRap M6.
Thank you for sending us your question.
