Re: 3D Printing - which process?

Yep,

The Eden is the best I've ever seen for resolution. Lots of different
materials as well.

Were looking at buying the smaller one for in house stuff. Same resolution
as the big one, just a smaller work envelope, and under 60K. Cost of
materials is the big question.

I am just finishing a enclosure for a client that houses an
electronic/pneumatic product. It's made of 3 parts and the next step is
Rapid Prototyping of the model parts. I know there are quite a few here
that have used this process and probably have valuable opinions that they
wouldn't mind sharing.
What sort of finish, structural integrity do the various 3D printers
produce? There are quite a few of these machines around our way now, but
it's difficult to get an objective opinion on pros and cons of each.
Ideally I would be after RP that would take minimal finishing, to use as
a
pattern for investment casting and has a reasonable amount of strength.
We
would use these initial RP samples to fit internals of device and have
the
machine used by a limited number of people to get feedback.
Can this be really be achieved with items produced by rapid prototype. I
know all the advertising blurb says this is possible , but in the real
world is this actually so.
Initially the quantity would be quite low hence investment cast or
similar
process. If product starts selling in numbers, material would switch to
plastic and injection molded dies would be required.

Would much appreciate any input from those who have used the process.
Cheers

I have had the best success with Objet prototypes. The resolution is
great.
And the cost is better than SLA, but not quite as cheap as some of the 3D
printers (FDM). There are several materials to choose from for the Objet
prototypes, but most are similar to acrylic in material properties.
