I am working on a project where I would like to laser engrave text into clear acrylic and fill it in with paint. I am hoping for suggestions about how to best color fill laser engraved acrylic.
I am having a problem with the background of the engraved area being frosty, which is fine when I am filling with white but looks bad when you fill any other color. Does anyone have experience with color filling acrylic successfully?
In my research I have come across some possibilities. It seems like extruded acrylic engraves more clearly than cast, but in a video I saw it still seems like it is pretty frosty. I also have seen that some people have done out of focus printing to melt the acrylic making it more see through. Has anyone been successful with getting an engraving to be see through?
Another issue I am dealing with is using regular acrylic paints to fill my engravings, I am having trouble getting it to fill in correctly and sometimes when I sand it the paint comes out of the engraved part. Maybe I could try a deeper engrave or a different type of paint. I have seen that people recommend rub n buff paint for this use. I would ideally like the paint to fill all the way so it would be flush with the top.
Thanks for any advice!
