Display Anomaly 1.10

Bambu Lab Software Bambu Studio
1

I just installed Bambu Studio 1.10.00.89 on a Mac with with OSX Sonoma 14.7.

I design my 3D models with very thin (0.001 mm) support planes to keep items with the same color grouped together*.

In version 1.09 these planes did not show up, but in 1.10 they show up as a red color that does show up in the filaments screen and I can’t find a way to turn it off. It makes it difficult to view the slice preview.

  • in the model I design each color as a separate object separated vertically. The thin planes keep what would normally be separate objects together. I can then separate the imported model into parts, apply the correct colors and merge the parts together. The planes don’t affect the slicing nor the final print.

I’ve attached Demo.3mf that shows the issue.

If you import the file into Bambu Studio, it creates a single object, OpenSCAD Model, with 5 layers. Split the object into parts and there are now 5 separate layers, OpenSCAD Model_1 through OpenSCAD Model_5. Change the filament color for each layer as needed. For this demo, layer colors from top to bottom are green, blue, white, red and white. Not that Bambu Studio splits into Parts, the order of the parts may not correspond to the height of the layers. Click on the OpenSCAD Model at the top of the tree and split to objects. There are now just the 5 objects, OpenSCAD Model_1 through OpenSCAD Model_5. Group select them all then select Merge to create an assembly. It doesn’t look that good in the preview, but if you slice it, the Preview pane with the Color Scheme set to filament will show you what it looks like.

That is, it looks fine in version 1.9.7.52, If you look at it in 1.10.00.89, not so much. There are several thin red planes. The red doesn’t match any of the colors on the Line Type color scheme and thus can’t be turned off. These planes correspond to thin support planes needed to keep the piece of each color layer together when splitting to parts. These layers are 0.001mm thick and do not affect the slice or the print. Even though it doesn’t look so nice on 1.10.00.89, it prints fine. If there is another way to keep layers together, I’m open to suggestions. The alternative would be to import 5 different .3mf files, which is less convenient.

Note: If you do try printing this you need to add a Height Range Modifier and set the fill to 100% for heights 7.3 to 8.7 mm. Without this the infill interferes with the top color. If anyone knows a better way to fix this, I’m open to suggestions.

Thanks,
Mark

I think it’s this new feature (always show shells in preview):

Showing the 3D shell in the preview mode, so if you turned off all lines you would see a ghost of the model. I think if you turn it off you will not have this issue?

That model has problems. It wouldn’t render correctly in Studio 1.10.0.89 for Windows 10 and when I exported the STL, as I feared, the model has a lot of problems. This is opened in 3D Builder for Windows. The Bambu Studio code uses the same libraries that 3D Builder uses.

The model as it renders is a layer cake of 5 objects. Was that the design intent? Because if it was, it cannot be rendered as is.

As an FYI. One big reason why I abandoned OpenSCAD was because it struggles with providing intact mesh files.

Even when I break it down into parts as you suggested, what I the slicer sees are rows of 2 dimensional parts with gaps.

In short, I don’t believe this model can be properly sliced. I also tried it in orca.

Here’s what it looks like when imported into OnShape. Not much better.

I double-checked using a Mac.

As usual, I concur with @Olias.

Thanks,

Changing the “Always show shells in preview” setting did just what I wanted.

Thanks for trying it. I agree. This is not a valid solid as is. This is by design.

This is actually 5 solids (one for each color, except two for white) separated by height. You need to split the model into parts, assign filaments to each part, then split to objects and merge before slicing. The two white solids can’t be combined as their union creates multiple solids.

The intent is to be able to create and import one .3mf file rather than having to create and import five. The latest development version of OpenSCAD has a one button click to create and export a single .3mf file, which opens Bambu Studio with the model ready to split, color and slice.

Glad it helped, I think I get it now. You have a complex bottom layer, multiple colors, text, designs here and there and you don’t want to have to paint individual pieces when you change the color scheme, or set the color scheme the first time, so you did this mad scientist solution.

I am sure there is a better way to do that, but I have no idea what it is :grin:

I have to concur with @lenyo. I’m not sure if there is a way to MacGyver this thing into cooperating with the slicer. Although I love a challenge, this one has stumped the band.

I appreciate the replies. I’m new to color 3D printing (since I got the AMS lite). Although what I’m doing is probably more like 2.5D.

How do others handle color? Do you manually paint the model in the slicer?

Again, what I have come up with does slice properly. The OpenSCAD script is very easy to modify to change the content on the print.
