In the comparison photos, is the poor quality one from something like a MakerBot? Maybe I've never seen a close-up photo before, but I always thought they created higher quality than that.
Yes it is. Extruded pieces can be pretty gnarly. This is exacerbated at small feature sizes, which is what you see here, especially on the birdcage which is about 3cm tall. To be fair, most people would clean that birdcage up a bit before showing it to anyone.
Most of the objects you see on the page have been cleaned up. For instance, over the "Accessories - Form Finish kit:" heading you see a part that hasn't had its temporary supports removed. The bracelet is a little furry on the bottom. It looks much better near the top of the page where it shows in a montage after cleaning.
