.3mf is not exclusive to Bambu as far as I know. Sadly people also upload those on printables with no .stl as an option.
But I get your point that it is an helpful file format for own projects or in companies. But for a 3d model sharing platform it seems a bit usless with all the different printer out there and bambu studio really could make it possible to ignore this settings.

Yes, they could, and should. As well as prohibit uploads without the raw model.
I think Bambu’s idea of creating multiple, printer-specific files, is doomed. There are just too many variables involved.
We will not reach their goal of click-and-print models until there are industry-wide standards for software and hardware that would allow a standard file format. Having different profiles for every possible printer/nozzle/filament combo is just unmanageable.
Imagine the difficulties creating and exchanging a paper documents if you had to specify the speed of the print head, the duration of the inkjet spray, how many jets to open for light gray text vs black, etc. Oh, you want to use the laser printer instead? Sorry, you’ll have to change all those settings…
We need the 3D print equivalent of a PDF, but we are a very long way from that nirvana.

I think it should be mandatory to include the raw files.
No uploads should be allowed without the raw files.

If you open up a 3mf file you don’t get the prompt.
If you create a new empty project and then add the 3mf file you don’t get the prompt.
If you create a new project, then add anything to it - such as a dummy cube object, then add the 3mf file you do get the prompt.

Exactly, you have to have a model already open for the proment. Apologies for not mentioning that. I’ve always got a window open with something in it already. Rarely do have have a blank project open.

Cough, the raw Step files, no one wants stl’s

Ideally, I’d like the Fusion .f3d so I can make stuff fit my need.

This would help so much, I really hope they just implement the prompt whether you want just the geometry or the entire project every time you open a 3mf file
There should be an option in preferences for:
- 3MF opening default behavior:
- Open whole project (default, as it is today)
- Only import geometry
- Always ask
This would resolve all our pain points and let us avoid addin dummy primitives just to be able to import an object. I’ve got an A1 Mini like a week ago and I’m already tired of getting all my settings and even printer and/or plate and/or nozzle changed at will.
Just now I didn’t notice the project changed to the Smooth Cold Plate and got a failed print after 2 hours and wasted ~100grs of filament.
This shouldn’t be the expected default behavior at all.
Of course, the other option would be for MakerWorld to allow downloading geometry files only instead of full fledged 3mf project files. We ain’t a mass producing printing farm with standarized machines, we’re end consumers lmao.
It will always prompt if you drag the file into Bambu Studio UI.
No, it won’t. The only way for that to happen is to have another model already in the current project/plate.
If you open from scratch/zero it will override absolutely all your settings.
Apologies, I tend t always have something open, computer never gets switched off.
I don’t often drag a .3mf into the slicer, but I think it is treated the same as closing the current project (which generates the prompt) and then opening a New project. The prompt is asking if you want to discard the current settings or save them to a profile before closing the project, not if you want to transfer the current settings to the new project.
I’ve only seen the transfer option when changing a profile for an already loaded project…
The whole point in using a Studio/Makerworld .3mf is to have ALL the settings for a successful print. If you only want geometry, download the .stl or .step file. Or download the .3mf and be prepared to review all the settings.
If you click on the small „cube with +“ symbol in the slicer prepare tab you can add the .3mf file and it will ask if you want load geometry only.
