thanks kind of. Depends on where type of 3D you mean. I did a 3D engraved and painted puzzle once:
What i would really, really like to do is save up for a UV printer and do textured puzzles on acrylic, since you can essentially 3D print with ink from what I understand — basically, building texture with clear resin and it lays ink on top of that. But, then you could feel the bark on the trees, the ripples in the water and so on. If I only had $30k laying around lol.
