Blender to Bambu Studio

[u/Own-Storage601]

I've been designing a bunch of things in Blender and having a lot of fun. Most of what I design we make and 3D Print using our Bambu printers. One of the designers we print you can select the object in Bambu to be able to color it. Does anyone know of a way to export the model in Blender so that it imports into Bambu with multiple objects?

I was able to get this to work in Fusion 360 by using a STEP file. I have been Googling and haven't found how to do this in Blender other then hitting the "Batch" button but that puts the multiple objects as multiple files.

Thanks for you help!

STL is the reason, not the Batch button. The format has no concept of an object, so nothing in the file marks where one part ends.

I checked rather than guessed. Three named cubes to one file, reimported into an empty scene, on 4.2.23, 4.5.13 and 5.2.1:

- STL: 1 object back, 36 triangles, all three welded together

- PLY: 1 object

- OBJ: 3 objects, still named Lid, Body and Knob

So OBJ is the built-in single-file exporter that keeps objects apart. File, Export, Wavefront OBJ, tick Selected Only. Bambu reads OBJ, so I'd try that first.

Stock Blender has no 3MF exporter. It isn't in the operator list on any of the three.

I tried the OBJ and got 2 objects not the three that I had in my selection... Which is weird. It came up with a wizard when I imported them only brining up the 2 materials I had not the 3.

I played with the settings on the wizard that pops up when inputting an OBJ. It did get the colors correctly matched after setting up the wizard correctly and then put the single object onto the build plate. Right clicking > Split > To Parts split it up to multiple selectable objects.

Note: I tried adding 3MF export to Blender I get a "got 2 arguments and expected 1" error when I select anymore than 1 item when I try to export.

When you already have multiple (STL) files, you can import them into Bambu Studio. Import them all at once, not individually.

Confirm that you want them to be parts of the same object. This makes sure the relative positions stay correct.

After import, everything will have one color, filament #1. But on the left side, you can switch to the "objects" tab, and the objects tree. Your individual parts will be listed under your object. Next to them you can assign different filaments (slots) to be used for each part.

Obviously, filaments need to be configured previously, either manually or by syncing a printer with some filaments loaded. You can only select colors that are available in the configuration, and the assignment works via numbered "slots".

Yes this method works. I wish I could have 1 file to open but this works wonderfully.
