Reply To: Question about removing gradient lines

If it’s from Shapeways it is either Acrylic (Fine Detail) or Nylon (Strong & Flexible). I’m not sure if either of those is affected by acetone. Your best bet is simply take some 300+ grit sandpaper and gently hit the areas that are most noticeable.

Another option, I would experiment before using a printed piece, would be to get some Auto Filler Primer spray paint. Shoot the filler primer then lightly sand. The filler primer should fill, at least partially, the layer lines on the print.
