I'm sorry if you were not aware that 3D printed items are done layer by layer, that's how FDM printing works. They melt plastic and print one layer at a time, so layer lines are always visible. We print our FDM items at 0.2mm resolution which is the industry standard for terrain. These items aren't resin printed pieces, which the industry standard print layers are 0.05mm in height which are almost unable to be seen by the naked eye.
