Artifact in Orcaslicer Preview? why?

[SV08_user]

NOTE: Fixed, it was in the TinkerCAD design, which I could not see until I added a flat piece to the surface*

A MASSIVE THANKYOU TO EVERYONE FOR THE HELP!!

As here now:-
*

The ironing on may be difficult to see but it does have Artifacts

The bottom item looks worse but it is just a clone of the first one. So this should be an exact copy of the top item.

I have seen physical artifact in actual prints, I am going to:-

a) check the STL, modify it to make sure that surface is flat. THIS FIXED IT

b) I use some software to repair my STL files, so I will try the Windows version built into Orcaslicer instead, or other STL repair or no repair to see if it is this. I use TinkerCAD to design STL and when I used to use Cura it the past it nearly always showed a message that most STL files where not watertight, so had to be repaired.

c) design a large plain rectangle and see if it happens to that as well or is it only more on complex parts.

I don’t use Orca, it crashes my desktop when I slice.
Gonna have to wait for someone else to help.

Hello,
Did you use fuzzy skin or adaptive layers to slice this model?
I sometimes got artifacts with these settings.

fuzzy skin or adaptive layers

Not asking for fuzzy skin, don’t know what adaptive layers are or how to

Will check the STL file which is good so far as I know

[mich0111]

With adaptive layers, it’s the slicer that determines the height of each layer based on its location and environment.
It’s a simple checkbox in the settings that can be set inadvertently.
I don’t say it’s the real cause but who knows…

I did see a similar post about Bambu Studio…the issue ended up being they need to check Detect Thin Walls. This fixed their problem.

TinkerCAD file looked OK but adding a flat plate to just touch the surface showed the artifact’s. So these where on the design now fixed
