Multi-part downloads arrive as separate objects
A multi-part model reaches your slicer as separate objects, one per part, when you use the 3MF or OBJ downloads. An STL is one welded mesh.
Parts that touched each other used to be exported as open shells, and slicers dropped layers from them. That hit 32 of the 60 newest multi-part models. Every object in the file is closed and printable now. Separate parts come through as their own objects, parts that touch come through as one object per connected piece, and part colours still come through, with Bambu Studio keeping them.
Smaller changes and fixes
- 39.01Fixed
Builds finish in a background tab.
Switching to another tab mid-build used to stall about 1 build in 25 (4.2%) for two minutes or more. The build now finishes while you're away, and the preview picture is taken when you come back.
- 39.02Fixed
You stay signed in.
A login lasts 30 days from your last visit, where it used to end 7 days after you signed in. If it does expire, the build page offers to sign you back in.
- 39.03Fixed
Builds work on Safari 27.
Most builds on Safari 27 were failing. A failed build now retries in a way that works there, and the page may pause for a moment while it does.
- 39.04Improved
Home page rewritten and Info menu added.
The home page is rewritten, and the header has an Info menu holding the Guide, the Blog and About.

Fortnightly email about your published models.
If people downloaded or remixed models you've published, a "Your models are loved!" email tells you which ones and how many, once a fortnight. You can switch it off in the email preferences on your account page.
