Paint Feature Sometimes Ignored

Bambu Lab Software
1

Occasionally I’ll have prints that have a small section of a different filament and for some reason it’s not respected in all areas. I’ve attached several screenshots showing this issue:

  • In the Prepare section of the slicer it properly shows all colors where they’re painted
  • The Preview section however only shows the primary colors and the 3rd filament is missing from the report
  • Even the image shown on the printer shows the 3rd color in place but missing from the print

This example is pretty basic and not a big deal but I’ve also had the problem on larger designs that have held me off from printing them. Hoping someone else has run into this and has a fix. I’ve replicated the problem on Bambu Studio ver 1.4.2.13 on macOS and Windows.

thanks for reporting this issue

could you share the 3mf for us to have a debug?

Sure thing, I didn’t see a way to attach a file to a reply so I uploaded it to my Google Drive.

I had this happen on a print. I did the poop bucket and wanted the logo in green. Matte gray bucket with green BL logo. Printed the bucket and prime tower, it did filament swaps and purged. Except it never printed the green logo.

I think about reprinting the bucket because I really want that logo in green. I just don’t want to waste the filament. That said, when I get ready to order my next X1 I’ll do another bucket and hopefully the green logo will print.

@technicalmacaroon thanks
we will check it

What happened, this has not been fixed? I keep painting a part then it changes straight back to the colour underneath when I slice it.

I just encountered this on one mine. First time in over a year of multi-color prints. It seems that the slicer is ignoring the painted surfaces and only shown the underlying color. Has there been any headway on this? I am on the most current version of Bambu Slicer.

This issue just started happening to me as well, super annoying. What is the fix?

If this issue is still being looked at, I’d like to provide a file that also has this issue - the strings in the racquet is not showing after slicing.

could you also share the 3mf here?
and give a picture of your case

I never saved it as a .3mf file but here is the source of the file if you want to try and reproduce the issue:

It was for my one of sons.

On that Racquet, go to the Strength tab and add a check for “Detect thin walls” and the strings will show up when sliced.

we need the 3mf which including the settings
could you reproduce it and share the 3mf and snapshot here?

thanks

Had the same issue for sume smal vertical engravings vith 3mf but works when exporting as stl.

Hey guys - I struggled with this until I read a random comment on reddit.

To make the Slice recognise the colours you must uncheck the Flush into this object

I hope this helps.

Since this has yet to be answered, it seems to me that the letters in the OP are not thick enough and are being lost during the slicing process.

For my filament cards it was an issue in that version of Bambu Studio. I’d been printing those cards for quite some time in multicolor without issue, and after another update to the slicer it started working properly again without any changes to the cards themselves.

Was scratching my head over this and it turned out to be layer height related. Make sure you have the correct first layer height and layer height for the print and that those are “thin” enough to produce your colored details!
