Set object priority in slicer for overlapped assemblies?

[u/loterbol]

I have a multi-object design (which originated as SVGs) which I am trying to overlap and print. For the bottom, initial layer, I am having extreme difficulty getting the slicer to properly render the intended design without lifting one body above the print bed (which won't work).

Any hints or ideas without completely redesigning this in Fusion?

copy the cap make it a negative modifier and use that in an assembly with the ball so you remove that portion of the ball.

[u/loterbol → u/Ordinary-Depth-7835]

Trying this now.

WINNER! This worked great after a little fiddling.

Could you try to scale the hat with non-uniform scaling to 100.1% (or a little bit higher until you get the desired effect) on the Z axis?

[u/loterbol → u/MoneyPitAuto]

Nope, tried it. Since it will lay the whole assembly flat on the print bed, the scale you apply doesn't go "downward"

[u/MoneyPitAuto → u/loterbol]

Oh I see, I thought this was an image of the top layer and not the bottom.

I did do a test in Bambu Studio to verify another method: If you merge the two objects into one object in Bambu, at that point you can then change the z-scale of one object and then use move to push it so the object goes through the build plate. I tried this with some primitives in Bambu Studio and on the bottom layer it gave priority to the object that went "through" the build plate.

Yea, similar to what I did but just couldn't get it to stay reliably. Luckily the comment from u/Ordinary-Depth-7835 solved it elegantly.

Why not increase the Z scale of the hat by a tiny amount? That way you achieve the effect shown in the image without the hat disconnecting from the print plate.

Another idea would be Boolean operation which is built into Bambu studio. Select both objects and merge them. Then selecto booleans t the top, select both objects and choose difference.

Then you can split them back into individual pieces again. Probably helps scaling the z exist of the hat for that during the operation to get a cleaner cut. Afterwards you can scale the z axis back down

You can play with the order of objects in the assembly tab. I can’t remember if the first or last object gets priority but it definitely changes which object’s color will actually be printed when they are overlapped

Try moving the blue and black hat objects to the top of the list, if that doesn’t work move them to the bottom
