Hello everybody.
Can someone in here tell me why i get ghosting through walls.
I have a multi color print, where the outside pattern also can be seen on the inside.
currently i print inside/outside order, havent tried the other way arround yet.

Could it be heat creep ?
Heat creep is a problem that happens in hot extrusion 3D printing processes (FDM (fused deposition modeling) and FFF (fused filament fabrication). It is the unwanted travel of heat up the filament from the hot end.
I might suggest the following:
-
Tune your filament. I see a lot of stringing going on indicating that you’re experiencing retraction issues.
-
Try using inner/outer/inner
-
The issue you’re seeing is likely being caused by different contraction rates. If you have control over the original design, try thickening the walls. You’re asking the filaments to not be influenced by dissimilar filaments. Increasing the wall thickness 2 more layers will help.
-
Increase the fan output and decrease the speed.
- This will encourage faster cooling of the filament thus firming it up on the next pass but it may be at the expense of layer adhesion.
- Alternatively, experiment with lowering the filament temp by 5 degree decrements as this may cause the filament to have less influence over the next layers. Again, this might cause issues with layer adhesion.
- Output speed is best controlled from the quiet mode in the print screen on the device page. It reduces the speed by 50%. Cooling can be found in the filament profile.

I dont know, but it only happens with the multicolor sections.
Hot filament on cooled filament ,was my thinking, due to its given form
I will try tinkering with your suggestions 
thanks alot for the detailed answer
