Thank you for that information. Where the print lines showed up on my rings are primarily convex surfaces. In areas such as the inside, or pretty much anything straight up and down the finish showed no lines whatsoever, it just had the fine grainy appearance once I painted it.
On the one ring where I have text that is freestanding and somewhat deep set the graininess in those inset areas is fine, as I plan to put black in there, or if the Stainless is deep in color the grain contrast against the polished face of the letters will be great. I'm mostly concerned about the lines on the top and bottom, on one ring they were pretty minimal, but on the other, the design of which I like better, they were pretty apparent and irregular. I am beginning to think based on your description that the polishing part of my order may not have happened, I might have gotten them straight out of the printer.
I've revised the ring model where the text wasn't deep enough and re-sized it a tad, will be doing the same to the other as well as seeing what I can do to make the top surface appear perfectly smooth in the preview and will order another set in polished white.
For reference I'm including a photo of the ring where the printing lines on the top and bottom were the less visible of the two. I sanded the entire ring with three different sanding blocks, going from coarser to fine then hit it with some primer and sanded it again before spraying the silver. the grain on the surface is still pretty visible as is the print lines top and bottom. It almost has the appearance of being made out of very fine sand up close.
I like the lines appearance here after the work I did to smooth them, I think they add a bit of cool detail but am concerned if I order the polished stainless steel or similar metal the surface and lines will be as rough as when I started on this one. The other ring required much more sanding to smooth out, I took it down to the point where no lines are visible as it has a curved design on the top and edges and the print lines were pretty irregular. So I'm trying to determine if the polished plastic versions finished surface appearance will correspond pretty closely to the metal version, or if the fact that the final is made from metal, and you heavily polish it, that it will have a nice smooth, solid looking exterior surface. The metal versions, while priced very well, are expensive enough that I'd just like to be sure before ordering.
