Hi, I’m quite new to 3d printing. But anyway… I ordered a model of a planet which I modeled myself (with actual surface structure like mountains etc). The service I ordered at used full-color plaster. As it’s normal there are tiny grooves in the printed object.

My question now is: does anyone know a technique or a product, that would help me accomplish a smooth surface? I heard some people use fine sandpaper but my fear is that the color and the surface would be “damaged”.

Thanks in advance, Sascha
