Multipart print. What determines what gets printed at the intersections of the parts?

Hi All,

Tough one to put into words…. Anyway I have an XL multi tool.  I am printing a multipart print.  It is the Star Wars robot  BB8, see attached.  I have a white shelled sphere as a part and the orange and gray “decals” as other parts. The Sphere is 6mm thick and the “decals” are 5mm thick.   The “decal” parts are positions so that they stick out .20mm outside the sphere.  What I want, is for the decals to be orange and gray through out their 5mm thickness.  What is happening is white is taking priority at the intersection of these parts.   See the image attached.   Is there a setting or technique in the Prusa slicer to specify what happens at the intersection of parts, ie which parts take priority?  Hope this makes sense.

Thanks in advance,

carmine

How are you colouring the parts?  Is that painting in the slicer?  Attached is a sample three-colour file; unzip it, import the three files together as *parts* and allocate each to a different extruder. You will find one colour is flush and the other protrudes 0.2mm.

If you print it use 0.2mm layers.

Examine the individual files to see the technique.

Cheerio,

Diem, 

Thank you for your reply. In my case I am importing them all as parts. Then I select each part and specify an extruder for each.   Sorry I wasn't clear about that originally.

I'll take a look at your example and see if I experience the same thing.

thanks!

Hey Diem, 

I tried your example.   I set each part to a different extruder.  In this case I chose extruder two (orange) for the word caster.  I see the same thing as in my original case.  When I slice the model and scroll through layer by layer I would like to see the word caster (3colourdemo3) as orange all the way through, but that's not happening.  The only part that is orange are the layers that are above 3colourdemo1.stl (the solid rectangle).   I was wondering if there was a way to make this happen.  

I attached my 3mf file with the model that demonstrates what I am saying.  Look at the object LEFT0. I have it colored with extruder 4.  You can see how thick it is by selecting it and moving it around.  Slice the model and then scroll layer by layer and you'll see what I am referring to after a number of layers the part LEFT0 is colored with extruder 3.

Here's the attachment.  Guess I had to zip it.

Is this what you're trying to do?

Diem,

Yes. That is the gist of it.  Did you get a chance to look at my example?  I wonder if there is an issue since my example is a sphere...   I can do something similar to what you did if I just have a rectangle and a cylinder and just move the cylinder inside the rectangle.  It appears to work, but I can't figure out why it isn't doing it in my example.

thanks!

Your example isn't thick enough.  The simplest method is to design the body and the feature, subtract the feature from the body to make a tailored void and replace it with another copy of the feaure saved seperately and allocated to a different extruder;.

Cheerio,
