Last June I had some puzzle pieces printed in "processed versatile plastic". The prints had a beautiful, smooth finished, and the pieces fit together beautifully. Last month I had the same pieces printed with exactly same order, and they surface finish was very rough. I tried to make them work, but the pieces bound together, and required significant sanding to be smooth enough to fit together. Sanding removes much of the color. Thinking Shapeways perhaps skipped the "processing" step, I asked them to re-make the parts, and they agreed to do so. There was some improvement the second time around, but the finish wasn't nearly as nice as what I received last June. Have others experienced this sort of inconsistency? Was the finish I received last June just a fluke? Below is a comparison of the finishes. The squares about 6cm (2.4") across.
