Bondtech Update on INDX Nozzles.
Hello dear Founders,
As promised, here’s an update on the INDX nozzles.
The nozzles supplied with the Founder Edition are surface-hardened, not fully hardened as originally advertised, and we apologize for getting this specification wrong.
Since our previous communication, we have been running comparative wear tests to understand what this actually means in real-world use. These tests are taking longer than initially expected, but in this case, that turns out to be a good thing.
With standard carbon-fiber materials, such as PETG-CF and PA11-CF, we were not yet able to wear down the current INDX surface-hardened nozzles to the point where it would affect print quality. Our testing units have gone through 10 kg of PC-CF with no visible wear.
Prusa is doing more extensive testing on their testing print farm and the results so far are consistent with ours. Their PETG-CF test nozzles have each printed around 10 kg of material, PC-CF nozzles around 5 kg each, and PA-CF nozzles around 2-3 kg each. They have measured some minor wear at the nozzle orifice, but so far without any corresponding change in extrusion width, print accuracy or visible print quality. Prusa also uses PETG Ultraglow as an accelerated wear test, as this filament is known to wear out even most nozzles on the market at a fast rate.These nozzles are not suitable for use with PETG Ultraglow for this reason.
Any nozzle, hardened or not, will eventually wear out. That said, if your main use case is printing pretty much only abrasive materials continuously, the current nozzles are not the right solution for you**.**
We are investigating a more wear-resistant nozzle solution for these extreme use cases.
Regardless of the encouraging test results, the specification you purchased was not the specification we delivered. Here is how we are going to resolve that - you choose whichever option fits you best.
Option 1 - Keep your INDX, with compensation for each affected nozzle:
- $20 / €17.50 in Bondtech Store credit per nozzle, or
- $15 / €13 as a cash refund per nozzle
For a complete kit, that means:
- 8-tool INDX kit: $160 / €140 store credit, or $120 / €104 cash refund
- 4-tool INDX kit: $80 / €70 store credit, or $60 / €52 cash refund
The amounts are based on the average percentual price difference between standard and fully hardened nozzles on the market.
Option 2 - Return your INDX Founders Edition for a full refund, at no cost to you, no questions asked, if the current nozzle specification doesn't fit your use case.
To claim either option, submit a ticket at bondtech.se/contact with:
- your order number
- your choice: store credit, cash refund, or return
We'll confirm your claim and process it as quickly as we can. If you have questions before deciding, ask them in the same ticket and we'll answer there.
These two options are how we resolve the nozzle specification issue: by claiming one, you accept it as the resolution of this matter. This does not affect your further warranty for anything else - that remains exactly as it was.
Please let us know your preferred option by mid-september. If we do not hear from you by then, we will consider the matter inactive and close it for administrative purposes. This will not affect any rights you may have under applicable consumer protection laws, and you are still welcome to contact us about this matter within the time limits those laws provide.
We apologize again for the incorrect original specification and for how long it took us to provide a clear resolution. We wanted to complete enough testing to give you a meaningful picture of the actual nozzle performance.
