I have to mix elements created with FDM printer with other ones created with resin printer.
Any idea how to imitate the PEI sheet texture so that I can apply it onto the surface of the models which is created on a resin printer?
Well maybe this can be helpfull: GitHub - TengerTechnologies/Fuzzyficator: (Work In Progress) A Gcode postprocessing script to add non-planar "Fuzzyskin" to top flat surfaces.
Most slicer have an option to create “fuzzy skins”. Fuzzyficator adds the same for the top layer.
The nice thing is, that is explained how it is done. And I think this is maybe useable for grasshopper too (although I think there might also be options to work with “material” settings in Rhino, when finishing a Step or stl file).
How it is done (my words):
- For the walls the curve the nozzle follows is changed so it makes very many small curves in/out. The curves are generated at random. The things to control is frequency of the curves (how many per distance) and the range the nozzle moves outside/inside the curve.
- For the top, the same but now the nozzle is moved up/down. Same controls.
BTW: Most slicers (also for resin) have options for skin-changes. The best way to camouflage little errors.

Thank you Quan Li!
Basically I want use it for triangular or quad surfaces. I does not really work for me. It does not cover the whole surface. Also changing the Perlin noise slider I cannot see to much difference in variations.

Hello
You can’t see something if mesh is coarse. And as you want to print it you need a fine resolution. Fine resolution means a mesh with lot of faces and lot of vertexes. @Quan_Li has given you the solution.
For viewing only, you can use procedural texture and use it as bump. It is more a Rhino option but could be doable in Grasshopper.
Can you attach the definition please?
No
As I said you have the solution and surely another from @Eef_Weenink. It seems you don’t even try to understand what is done for you. And you have been here for 10 years!
Hi Laurent, thanks for the nice comment! 
Can you explain please why it is your image without definition so huge help for me? I can see a Cluster with about 30 parameters.. (Cluster means that you don’t know what is happening inside…)
In the future can I ask you to refrain from negative personal judgmental remarks. How do you know that I did not try just being stupid?
I thought this forum is for helping and not for humiliating each other.
I didn’t try to humiliate. Don’t reverse things, you just posted Quan Li definition with a curve (a square) and you just said it didn’t work.
Did you try to refine it like I said ? Apparently No!
Look at the magic, just use the option of remesh, put a low Max Edge Length
My image was indeed not useful for your need as just useful for rendering.
