Fonte Boa,
Can't answer your question but my friend had one object printed at a local shop and he was able to smooth out rough edges with a very fine sandpaper. If I were to guess, I would bet that getting a final product with a smooth finish would cost more. It may depend on the materials used. Did you look at some of the objects that were shown by customers in the Shapeways forum?
I can't wait to see a picture of your first printed object and get the final word on all your research...

Maybe using a high resolution one?! But you probably will must pay for this quality.
Micheus, even in objects printed using 0,1mm height layers those lines use to appear. The instructions of Shapeways site about this mention this problem.
I've already mentioned at EDIT6 above about a 3d printer that use resin and a stereograph process. I was suspecting that would be the BEST 3d printer... So, Micheus, i've just found it at top of the list in the last link you posted!!!
Formlabs Form 1 is its name: http://formlabs.com/
I'll have to take a look at the characteristics of a piece printed in resin using that device and who print using it.
Anyway the video is impressive imo:
Take a look about this process callde stereolithography:
Oort, thanks, you had a nice idea: i'll take a look at shapeway forum to see some pieces printed.
About the sandpaper, i think this isnt a good idea for very detailed objects, no?! :\
Yeah, I saw that these resin machines have the best result, but if you think about print in colours, then they aren't so good.

The Ceramic material seems do not have this problem, but of course it's not so resistant.
I found the Vimeo video in the Formlabs home page more "clear" about the process.
Did you noticed this comment in its Material specifications: Long shelf life when not exposed to light
I've already noticed that formlab observation about light exposure... What would be the problem? Colour vanishing? I confess i didnt understood.
It seems that printer is just being pre-order: this isnt yet being delivered (just 2013 august)...
Let me ask a dumb question:
is it possible to paint these 3d printed objects?
I mean, not during the printing, but after done...

Degradation (check here). I believe that it can break easy with the time, like I already noticed with the fluorescent starters (the external piece breaks easy after a few years exposed to the light)

Fonte Boa,
Yes, I guess sanding would not work well on a highly detailed 3d print. The one my friend had was not that detailed. He was lucky enough to get a free 3d print when he went to a local company for a demonstration.
Sounds like the status of 3d printing is not what it is made out to be in the press, as if it is the next best thing since sliced bread... much like the over praised electric car...
I wonder if you could coat the 3d print to smooth it out and then use the 3d print to produce a mold, which you could fill with a wider range of materials???
