Delete a filament profile in three steps

To delete a filament from Bambu Studio, open the software and go to the Filament tab on the left sidebar. Find the filament you want to remove, right-click on it, and select Delete from the menu. The filament will be removed immediately and will no longer appear in your filament list.

If you cannot right-click on the filament, make sure you are clicking directly on the filament name or thumbnail, not on an empty area of the panel. Custom filaments you have created yourself can always be deleted. Filaments that came built into Bambu Studio (the default library) cannot be deleted, though you can hide them from view.

After deletion, any printer profiles or print settings that referenced that filament will still exist, but you will need to reassign them to a different filament before you can use those profiles again.

Key Takeaways

  • Right-click any custom filament in the Filament tab and select Delete to remove it permanently.
  • Built-in filaments from Bambu Studio cannot be deleted, but you can hide them so they do not clutter your list.
  • Deleting a filament does not delete print settings or printer profiles that used it — you will need to reassign those to a different filament.
  • Deletion happens immediately with no confirmation dialog, so double-check you are removing the correct filament.

The difference between deleting and hiding filaments

Bambu Studio distinguishes between filaments you created yourself and filaments that shipped with the software. You can delete only the ones you created. For the built-in filaments — such as the standard PLA, PETG, and TPU profiles — you cannot delete them, but you can hide them from your list so they do not take up space.

To hide a built-in filament, right-click it and select Hide. The filament will disappear from your active list but remains in the software's library. You can unhide it later by going to View (or a similar menu option depending on your Bambu Studio version) and toggling the visibility of hidden items back on. This is useful if you want to keep your filament list clean without losing access to the defaults.

What happens to your print settings after you delete a filament

When you delete a filament, any print profile or printer configuration that used that filament does not automatically update or disappear. Instead, those settings become orphaned — they still exist in Bambu Studio, but they reference a filament that no longer exists.

Before you delete a filament, check whether any of your active print profiles depend on it. You can do this by looking at your Process tab and reviewing which filament each profile is set to use. If a profile uses the filament you plan to delete, change it to a different filament first. After deletion, if you try to use a profile that referenced the deleted filament, Bambu Studio will prompt you to select a replacement filament before printing.

How to create and manage custom filaments

Custom filaments are the ones you can delete. You create a custom filament by clicking the + button in the Filament tab, filling in the filament name, material type, and other properties, and saving it. Once saved, it appears in your filament list and can be used in print profiles.

If you create a filament by mistake or no longer use it, deleting it is straightforward — right-click and select Delete. However, if you have already built print profiles around that filament, you will need to update those profiles to use a different filament before you delete it, or be prepared to reassign them afterward.

Recovering a deleted filament

Bambu Studio does not have an undo function for deleted filaments. Once you delete a custom filament, it is gone permanently. If you realize you deleted the wrong filament, you will need to recreate it manually by entering the same settings again.

To avoid accidental deletion, take a moment to confirm you are right-clicking on the correct filament before selecting Delete. If you use a filament regularly, consider keeping a note of its settings (material type, nozzle temperature, bed temperature, and any other custom values) so you can recreate it quickly if needed.

Frequently Asked Questions

Can I delete a filament that is currently being used in a print job?

Yes, you can delete a filament even if a print profile uses it. However, the next time you try to use that profile, Bambu Studio will ask you to choose a different filament. It is better to reassign the profile to a new filament before deleting the old one to avoid confusion.

Why can't I delete a filament from the built-in library?

Bambu Studio locks its default filaments so you do not accidentally remove materials you might need later. If you do not want to see them, use the Hide option instead. This keeps your list organized without losing access to the standard materials.

What if I delete a filament and then want to use it again?

You will need to recreate the filament manually by clicking the + button and entering the same settings. Bambu Studio does not keep a backup of deleted custom filaments, so write down the filament properties before you delete it if you think you might need it again.

Does deleting a filament affect my printer settings?

Deleting a filament does not change your printer hardware settings. It only affects print profiles that referenced that specific filament. Your printer itself will continue to work normally — you just need to assign a different filament to any profiles that used the deleted one.
