Filament profile not saving as user preset

Bambu Lab Software Bambu Studio
1

Hi all, I bought som Siraya Tech TPU Air for a project I’m working on and I’m trying to save the profiles for the different durometers provided by ST. I’m able to save them and they show up fine while I have the provided project with the profiles open, and they even show up under User Profiles. But if I close BS and reopen it it’s gone. BS 2.2.0.85

What it looks like after I save it as a user preset:

When I close and reopen Studio:

Profiles:
Siraya Tech TPU Air H2D 260C 0.4mm 20250724.3mf (37.6 KB)
Siraya Tech TPU Air H2D 270c 0.4mm 20250724.3mf (39.4 KB)

Looks like it’s saving, but they aren’t showing up in Studio? Odd

EDIT: Looks like the .info file is missing data. Not sure if it’s caused by the new version of Studio?

When creating the filament from scratch and making individual profiles, the .info files have the correct data and the profiles save properly. It must be an issue with the profiles provided by ST

Has anyone come up with a workaround for this? I’m not seeing the full data in the .info files once saving my Siraya Tech config as as a user preset.

You can’t save it from the file. You’ll have to use the profile in the files they provide and manually make one and save it. Then it’ll have the right data in the .info file for BS to work with it

Thanks. Manually recreating it was the only option that worked. I just had two instances of bambu studio open and just copied everything over. Digging into the json I saw that there was dependencies on other Siraya Tech filament configs, so that may have been part of the problem.

Almost a year later, I still have the same problem – unfortunately, it has not been resolved.

I found the solution.

The filament profile was saved correctly in:

Library/Application Support/BambuStudio/user/[user ID]/filament

However, Bambu Studio did not show the profile again after restarting because the inherits entry referenced another custom profile:

"inherits": "Siraya Tech TPU TPU 95A @Bambu Lab P1S 0.4 nozzle"

That parent profile was apparently not available as a permanent user preset, so Bambu Studio could not resolve the inheritance when starting.

Changing it to:

"inherits": "Generic TPU"

fixed the problem. After saving the JSON file and restarting Bambu Studio, the Siraya Tech TPU profile appeared normally under the user filament presets.

This way, all the original filament settings remain intact, and there is no need to recreate or manually copy dozens of values.
