Top Layer color going through infill of model

I’m trying to paint the windows and lines on the chimney. When I apply color, it goes through the entire model increasing print time and lots of poop due to color changes. I’m trying to get only the top layer painted. I have tried using modifiers, paint by layer, etc. No luck. Now I’m new to 3D printing and using slicers, so who knows what I’m doing wrong!

A1 printer with AMS
have set paint layers to 1, etc.
Using basic PLA
The model I’m trying to paint for my daughter is on Makerworld here: Tea Light Haunted House by JamesThePrinter MakerWorld: Download Free 3D Models

Thanks in advance for any guidance offerered!!!

If you only want the top layer a different color you can do that in the preview panel. Right click on the layer slider at the topmost layer. Change filament. Re slice.

You can also use the paint tools “vertical height range” mode to try to do the thing but will rarely give you exactly 1 layer of color in the final model.

Thanks for the help! when I try to change the filament type by right clicking on the slider, the option to change filament is not available. Not sure if you had a chance to see the model I’m practicing on, but as someone new to this, I don’t undertand why the color goes deeper into the model when I’m only painting the top layer. From what I’ve read, I guess it can’t be controlled?

Models

In Bambu Studio, move the back two parts to a new build plate.

  1. Window Frames.
  • Right-click the front part
  • Select Height range modifier
  • Set the range from 2.0 to 5.0
  • Select the layer range you set
  • Press the number of the filament you wish to use for the chiney or select the swatch on the same row and choose the filament.
  1. Chimney
  • Use the Paint tool type Fill
  • Hover over the chimney lines
  • Select the top surface lines
  • Repeat for the left and right sides of the chimney

The chimney model will take a while to print. The Fill type is the easiest to use; it fills correctly to make the colour show through.

The colour doesn’t bleed too far, at least not for me.

It only bleeds where the pointing exists.


Thank you for the detailed response!!! I was able to reduce the number of color changes and time to print!

You are welcome.

My aim is to help people know how to solve the situation in the future as well as the current issue.

I am glad I solved your problem.
