Ran13 (i always remember Ranxerox when i read your nick name here 
),
thank you VERY much for the info.
Very nice to know RepRap project: i'm just begin to read all those materials, but it seems user should acquire (if he doesnt want to build the printer himself) a PrusaMendel machine. This isnt yet clear to me: WHERE to buy one. It seems there is a vendors forum at RepRap page, but i'll have to verify their confiability...
Anyway, Ran, the link is fine: thanks!
Ah! The other option, MakerBot is a handsome machine: expensive, but pretty.
Where did you get the info it is "2nd most widely used 3D printer"?
I would like to found some comparision between this kind of end users machines, and what are the main differencials to be compared...
Micheus, thanks.
Oort, thanks too: i've already mentioned Shapeways above, but i didnt know yet about Quickparts services.
----------------------
Watching some videos about 3d printers and uploading some models just to verify how much ($) would it cost to have them printed, i noticed something interesting.
The costs are related to how many material will be used (cm3). So, if the models is SOLID the prices are higher than if they are HOLLOW (sorry for my english, maybe VOID is more adequated word).
Some videos of 3d printers working show this better: the fill of the piece isnt continuos, solid, but "full of holes", like a kind of net.
I dont know HOW to produce the kind of fill to a model.
Using Wings, i've just select a single face and apply Intrude command, just to generate a vaccum inside the piece (and of course a general "wall" with some thickness). Therefore, i didnt yet tried to upload a model like this: i'm afraid it isnt valid... I'll try and post here the result.
I've read in a Ran13 thread around about some Blender tools to deal with models to be printed. The video i've found is just partial (it seems training dvd with all the content is for sale), and there are tools to verify thickness etc.
My doubt is: if anyone wants to 3d print a model, what should be made about the piece filling? Blender tools treat this matter?
The main: a piece enterely hollow/void is less resistent than the pieces "fill with holes" (a kind of net)?
EDIT:
just a link to a video which shows that kind of filling i've mentioned ("fill with holes": dont laugh of my english, ok): for about 0'23" you can see what im talking about.
EDIT2:
Hey, Ran, just now i've noticed at the video about: it is a MakerBot machine!
EDIT3:
Sorry for extrapolate the matter, but this video affected my feelings.

I've found a comparison!

EDIT5:
And there an interesting competition here (the prize is a 3d printer):

EDIT6:
Another comparision: i've discovered a model that works with stereography and resin.
