The key to being a good engineer is to figure out how to do things on the
cheap... I'm not sure I'm actually good, but I'd like to take a crack at
it.. :)
I propose testing a bunch of this stuff cold - to prove out a method of flow
modeling.
I think one of these would be useful (and reasonably priced):

Wow that is REAL cool. The BIG application for this machine is making
casting molds and core boxes. I used a similar machine at the local college
to make these intake manifold molds and core boxes on a commercial version
that cost $50,000.

In case anyone needs it, I'm the only person I know that has a Zcorp 310 3D
printer in my basement. I'm cheap compared to a commercial operation. I
can make core boxes and even some direct molding patterns if I get the Zcast
materials.

Ben,
What is the size capability of your printer? I may be interested in having
some patterns made.
Thanks,
Larry
My printer is the original Zcorp 310. It can print an object 8" X 10" X 8"
I keep the resolution set at .0035" which is pretty much the best that it
can do. Good for making washout patterns for composites and prototypes. I
have made bigger pieces by gluing together sections (manifolds, etc.).
I run the machine a lot and it's very reliable. This is by far the lowest
cost way to make 3D models of the various art to part technologies.
Enter Zcorp on Youtube and you'll find several videos on this particular
model. There is even a video on making direct castings from molds made on
this machine.
I've never made an actual casting because it takes a special ceramic powder
which I don't have. I keep a generic powder in my machine which is (as I
understand it) mostly plaster and cornstarch. The binder is a water based
"glue". You might be able to make castings with the plaster powder. I
don't have a foundry in my garage (yet) so it will be up to you to
experiment.
