What is happening when you set a Paint Penetration Layer.
The term Paint is used in: Support Painting; Seam Painting; Color Painting.
I have used Support Painting and Color Painting but I don’t really understand what this is doing for me in the Strength setting in Studio.
There are default penetration layers in both top and bottom.
Does that mean it is going to “Paint” the top and bottom finish layers of a print at the number of layers set?
In Studio it has a default of 3 layers for the Bottom Paint Penetration Layer value.
is that the number of layers that will be extruded in the Bottom Surface Pattern I choose? Seems like that could conflict with the Shell Thickness?
Asked and answered.
It does mean the number of layers any painting will “soak” into.
If you do not paint, it doesn’t matter.
I agree that placing it into the strength tab is strange, it appears out of place and certainly out of context.
The tooltip help offers a rewording of the caption, the definition of unhelpful.
It’s probably under strength because if you have poor layer adhesion, something like letters on a sign could fall off. The number of shell layers, right next to this setting, is also going to affect it so it’s logical. I agree that the tooltip could be improved.
Has anyone gotten this to work yet?
I’ve attempted this multiple times and increased the paint penetration layers to >100 sometimes and in the actual layer breakdown, it still prints the same amount of layers. This feature doesn’t seem to be working.
Did you have text at the top or the bottom side of the part?
For me on the top, it did not have any effect, on the bottom it does.
Does this only work for text?
I actually am printing a fairly flat object that has varying heights on the top layers. It’s basically a sort of “crest” that has varying layers at the top to give the art on it a 3 dimensional look. But the paint is just 1 layer on top and leads to the black base filament showing through the colors.
So basically, just like you, it doesn’t work on the top at all. And I can’t tell if this is just a bug or if I’m not using it correctly.
Sorry, I should have said colors instead. Nothing to do with “text” 
No worries lol but yeah, colors on top for sure just don’t “penetrate” additional layers. No matter what you adjust that value to.
It’s looking more like a bug the more I mess with it but I’m not in any way certain how we would even get this addressed. And it sucks because this is a SUPER useful feature to counteract color bleed from a darker color underneath the top layer color.
On one of my models, it seems like the bottom of the coloring was kinda slanted. Somewhere at 5 layers deep tiny bits of coloring appeared and the closer to the top the area increased until the top layer having the full area. So I recognize your bleed through issue also.
On side faces it penetrates the part quite deeply.
It seems that the top and bottom penetration layers can be set by the appropriate penetration settings but it is missing side penetration and will do it’s own thing and cause bleed from the side.
I hope they can add side penetration layers setting!!!
Yes, I noticed same issue. Each layer, the paint area has different size until it reaches the top or botton, making inside colores to bleed. The only fix I see is to have objects separately, but it is not always feasible
