Slicing issue in Bambu Studio

Bambu Lab Software Bambu Studio

I am at a full loss here. I want to print this ‘card’ I made, and I cannot get it right. The idea is that the octagons and helmet are on the front and the ‘power’ symbol on the back of the card. I can build it super easily in TinkerCad with colors and look, but as soon as I import it into Bambu Studio, it becomes a problem. I tried to build in Bambu Studio, but lifting things up is a nightmare to get it to do it right.

I tried to build it many ways, but the final way that seems to work the best was to build it in 3 ‘plates’. Plate one, at .3mm is the ‘front’ of the card, so the octagons, helmet and a .3m piece of ‘card’. Plate 2 is simply a .4mm ‘card’. Plate 3 is a .3 mm ‘card’ and the power symbol. I combine them together and save as STL in TinkerCad, and import into Bambu Studio.

In Bambu Studio I split it into parts and re-assign the filaments to match my AMS so everything is colored correctly. 3 colors are used (red, black, blue). It looks ‘mostly’ fine (image 1 and 2). I don’t know why image 1 has a challenge showing the black power symbol, but its there and you can make it out. I assume its the software doesn’t like it since its flush with the ‘card’ piece. Then I slice it, and this is the issue I get.

For some reason, when sliced, most of the parts are lost (image 3 and 4). When looking at the slicing results (image 5) the blue is gone completely, so I know that its not just a visual aspect but that the software simply ignored most of the parts.

What am I doing wrong, and how can I fix it so I can print the card correctly and make sure that the two faces are not visible through the card? I may end up changing the colors later (darker card, lighter images) to help, but for now, I cannot even test print this card. I don’t know if it matters, but I have the P1S and a single AMS.

Thank you in advance for advice and assistance!

Hi, are you able to post your project file? It’s hard to determine what is going on based on a few select images. It sounds like maybe the parts are being surface-painted instead of using the assigned filaments (that’s been a common issue lately), but it’s hard to say (shouldn’t happen with STL format anyway). Another possibility is that some of the parts are too small/thin to be printed (based on layer height or line width) and the slicer ignores them (or mostly). And that’s just two out of multiple possible causes… there’s no one universal solution.

Thank you for asking! I was about to do exactly that and I actually figured out what the problem was. The ‘card’ as a whole object is 12 parts. The slicing was showing the card itself (those 3 plates) and only 2 parts, the last two parts. When I organized the parts in a different order (the 3 ‘plates’ first, followed by everything else) and sliced it again, it worked perfectly!

What did you mean by surface-painted by the way? I was using assign filament instead of painting to get the color I wanted, if that is the correct way to do it.

Ah, good call. Indeed the order of the parts can make a big difference! :+1:

And yes, assigning filaments to parts is usually much better (comes out cleaner) than painting anything. When painting is applied, it will often override the assigned filament, which can be confusing. In some cases Studio may apply surface painting to parts during import, or it gets applied for some other reason, and that’s not always obvious. So that’s what I was referring to, and sounds like you’ve got it dialed in already.
