Yes, you can change your Bambu Lab username through your account settings

Bambu Lab lets you change the username associated with your account, but the process depends on whether you signed up with email or a third-party login like Google or Apple. The change takes effect when ready across all your devices and the Bambu Lab app, though you will still use your original email address to log in — the username is what appears in your printer's web interface and in the Bambu Lab community.

The username change is permanent once you confirm it, so choose carefully. You cannot revert to an old username or use one that another account has already claimed, even if that account is inactive.

Key Takeaways

  • Your Bambu Lab username and your login email are separate — changing your username does not change how you sign in.
  • You change your username in your account settings on the Bambu Lab website, not in the mobile app.
  • The new username appears when ready on your printer's web interface and in any shared projects or community posts.
  • Usernames must be between 3 and 20 characters, contain only letters, numbers, hyphens, and underscores, and cannot match an existing account.

Where to find the username setting on the Bambu Lab website

Log into your Bambu Lab account at bambulab.com using your email and password. Once you are signed in, look for your account menu — this is usually a profile icon or your name in the top right corner of the page. Click it and select Account Settings or Profile Settings from the dropdown menu.

In Account Settings, scroll down until you find the Username field. It will show your current username and have an Edit or Change button next to it. Click that button to open the edit box.

Steps to change your username

Type your new username into the field that appears. Bambu Lab will tell you when ready if the name is already taken or breaks the naming rules — usernames must be 3 to 20 characters long and can only contain letters, numbers, hyphens, and underscores. No spaces or special characters are allowed.

Once you enter a valid username, click Save or Confirm. Bambu Lab may ask you to re-enter your password to confirm the change. Do this and the new username becomes active right away. You do not need to log out and back in, and you do not need to restart your printer or the app.

If you see an error message saying the username is unavailable, try a different one. Common reasons a name is taken include: another user already has it, you are trying to use a name you used before on a different account, or the name contains characters Bambu Lab does not allow.

What changes and what stays the same after you update

Your new username will appear in the Bambu Lab app, on your printer's web interface (the page you see when you type your printer's IP address into a browser), and in any community posts or shared projects. Anyone who has your printer's IP address can see the new username on the printer's status page.

Your email address does not change — you still log in with the same email and password you used before. Your printer's connection to your account does not break. Any files, print history, or settings tied to your account remain exactly as they were. If you have shared access to a printer with family members or colleagues, they will see your new username the next time they open the app or refresh the printer's web page.

If you cannot find the username setting

The location of account settings can shift slightly between app versions and website updates. If you cannot find the Username field in Account Settings, try these steps: first, make sure you are on the Bambu Lab website (bambulab.com) and not in the mobile app — the mobile app does not have a username change option. Second, look for a section labeled Profile, Personal Information, or Account Details instead of Account Settings.

If you still cannot locate it, sign out completely, sign back in, and try again. Sometimes the page needs a fresh load to display all options. If the field is still missing, your account type or region may have different settings — contact Bambu Lab support through the Help section of the website and describe what you see in your Account Settings page.

Usernames you cannot use

Bambu Lab reserves certain usernames for system use and will not let you claim them. These include names like "admin", "support", "bambulab", and other terms tied to the company or common system functions. If you try to use one of these and get a rejection, pick a different name — there is no way around this restriction.

You also cannot use a username that is already active on another Bambu Lab account, even if that account has not been used in years. Bambu Lab does not release old usernames back into circulation.

Frequently Asked Questions

Do I have to change my password when I change my username?

No. Your password stays the same. You log in with your email address and password, not your username, so changing the username does not affect how you sign in to your account.

Will my printer stop working if I change my username?

No. Your printer remains connected to your account and will work exactly as before. The username is just a display name — it does not control the connection between your printer and your Bambu Lab account.

Can I change my username back to what it was before?

Only if no other account is using that old username. If you changed your username and want to go back, try entering the old name. If Bambu Lab says it is taken, someone else has claimed it and you cannot use it again.

How long does it take for the new username to show up everywhere?

The change is when ready on the Bambu Lab website and in the app. If you are viewing your printer's web interface in a browser, you may need to refresh the page to see the new username. Other users will see the new name the next time they refresh their view of your printer or your profile.

What if I see my old username still showing somewhere?

Clear your browser cache or close and reopen the Bambu Lab app. Sometimes your device holds onto the old information until you force it to reload. If the old username persists after that, sign out completely, wait a minute, and sign back in.
