Improve Text/Logo Prints

Hello Community,

I have a small question.
I was finally able to properly export SVG so that Prusa Slicer does work with them.
I print an orange part with black logo/text.
The printing starts with the orange parts and then switches tools to print the black text/logo.
Because of this printing order, the black is leeching through the orange layer and this does create "less sharp" edges.

One way to circumvent this, is to create the logo/text as an individual part, then add the same text/logo as a negative volume-modifier to the orange part and then pixel perfect align the black text/logo and the orange part on top of each other.
Now, in the "part window" on the right you have to make sure that the black object is first and the orange one is 2nd...

As you can imagine, this is hilariously tedious and sometimes doesnt work at all.
Does anybody has other tricks i can use to force the printer to start with the text/logo first?

 

best,

Max

Maybe works :The logo/text extruder should be no. 1.

When I've done it I import the SVG to Fusion 360, create the base then do a negative extrude of the SVG to create a pocket, then do another negative extrude but this time create new a body which gives you the text as a perfectly aligned new body. You can then export all bodies as a single STL, import into slicer and then set each body to the appropriate colour.

That sounds a lot more complicated than it is but removes all the mucking around trying to align the negative space and the positive image

I do essentially the same thing in OpenSCAD, except I export each part as a separate STL, and PrusaSlicer offers to treat the parts as aligned parts when you load both parts simultaneously.  So as long as they are exported from OpenSCAD 'in situ', they will be properly aligned.

The key thing for getting the lettering to print first is as @Ro3Deee says - PrusaSlicer will schedule the filament with the lowest extruder number to print first, and then the others in numerical order.  So you need to load them in the correct order to make sure your text prints first.  A nice feature to add to PrusaSlicer would be to allow the user to choose the extruder order, or at least the first extruder, so that you don't have to keep re-loading filament in a different order for different jobs.

Yes, you are both right, changing the filament, so that the "logo color"  is in the first and the base color is in the 2nd extruder is a much betterr working solution!

Still it could be cool to create a way in the software to "prioritize" colors or parts to print first.

Thanks to all of you!
