[adam-puleo]

Bambu Studio Version

1.10.2.76

Where is the application from?

Bambu Lab Official website

OS version

macOS 15.4

Additional system information

CPU: Apple M1 Pro

Printer

Bambu X1 Carbon

How to reproduce

1. Load the attached 3MF file in version 1.05.00.61-20230 of Bambu Studio.
2. Click Preview
3. Observe that all letters and shapes are on all three sides of the object.

Actual results

1. Load the attached 3MF file in version 1.06.00.65-20230 or newer of Bambu Studio.
2. Click Preview
3. Observe that only a couple of letters and no shapes appear.

Expected results

The shapes should be sliced in the newer versions of Bambu Studio but are not. I noticed that this also happened in Prusa Slicer. I can find out which version if required.

I tried loading this 3mf in OrcaSlicer, Windows 3D Viewer, and multiple online 3mf viewers. None could properly render the text, many refused to load the file.

Likely the model is at fault here, not the slicer.

@LJKraus Because the surface of the text and the surface of the base are completely overlapping, and the text color is different from the base color, it is equivalent to a single surface having two colors at the same time. This causes a conflict when displaying the colors.

The file loads fine in Bamboo and Prusa slicers and I don't see anything about the model having errors so I don't think it's the model.

I have attached the model again. I think in the original post I accidentally saved it in Bamboo. If it asks you to convert to millimeters say no. Change the object named “Bottom” to a different color.

I understand why everything looks kind of weird in the Prepare view.

My question however is why in version 1.05.00.61-20230 everything is sliced properly (you can see this in the preview tab), but in versions 1.06.00.65-20230 and newer almost none of the letters are sliced.
