3D print devices and services

[Fonte Boa]

Thanks again, Oort and Micheus: you are great!

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:

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?! :\
