You can import a font into Bambu, but it is pulled from the font library on your computer, so you have to add the font to the font library and either restart bambu, restart your computer, or both. In my experience, it is finicky. I’ve gotten some to import but struggle with others. There is also a distinction between adding it to your user font library instead of “ALL USERS,” and that process is slightly different on mac and pc as far as I can work out. From my research online, it seems slightly more reliable on PC. I’m on mac, and I’ve only gotten a couple to work after quite a bit of frustration each time.
This is an old thread but I’ve been wondering the same thing and found this while googling. I think Bambu Studio saves your rendered text in the custom font in vector format but doesn’t embed the whole font into the file. So if someone downloads your model and does not change the text, it will print in the custom font. But if they edit the text object to say something different, it will immediately switch to a different font.
The way I found this is via a little experiment as follows:
I created a model in Bambu Studio that has a text object and uses the font “Gill Sans” and made sure it slices and prints properly etc
Then I closed Bambu Studio and deleted the font from my computer
I opened up the model again in Bambu Studio and the text object looks perfectly fine and slices fine BUT if you edit what the text says, it immediately switches to the first font in your dropdown list
P.S. While we’re on the topic of fonts… This is a separate issue but I’ve read in a few places that if you have a custom font that isn’t working properly in Bambu Studio, it may be because you need to reinstall it so it’s accessible to “All Users” on your computer and not just for the User you are logged in as.
