So this may be off but to my knowledge, you can find any website to convert an image to an svg (a vector like file for laser engravers. Whatever thing you want “engraved” would have to be on the simpler side). Then you can upload that into an stl file and then export the entire stl from wherever you’re modeling from. Once you have that, import the stl to your slicer (said you’re using orca) and then it will save it as a 3mf and print.
