RE: [rp-ml] Ceramic structures using RP

Bob

Nanoform isn't really aimed at the ceramic market. Prototool would be a
better comparison to Bluestone. Both systems are heavily loaded giving
good stiffness and thermal stability.

Jim

OptoForm is capable of manufacturing ceramic components, although there
are not too many of these systems around now. I believe there are still
a few of the original French machines running commercially and some of
the 3D beta machines are still in circulation.

Do the new resins, Bluestone from 3D and the Nanoform SLA from Somos
qualify
as ceramic materials?

LOM, SLS, and Z-Corp have ceramic type materials. Z-Corp is more of a
sand
type material for casting shells. LOM is not really a viable product.
SLS
ceramic materials are mainly academic. There is some SiC (silicon
carbide)
work out of the Univ. of Texas that has yielded promising results, but
it
has not been done on a large scale. We've had some ceramic parts made
for a
few customers, but not much.

Subject: [rp-ml] Ceramic structures using RP

Good morning,

I have a question. I just subscribed to this mail list so please be
gentle!
I've been working on a comparative analysis of the RP processes
(hasn't
everyone!?!) and I'm trying to determine which processes can provide a
part
using ceramic materials. Can someone please give me a list of
processes
that can be used with ceramic materials? I'd like to have some samples
made
to test the typical characteristics such as dimensional accuracy,
surface
finish, strength, etc. I will be testing all types of materials such
as the
plastics, metals, ceramics, and so on. I just want to make sure I
have
captured all the processes that can do ceramics.

Also, on a side note, I've been trying to get an .stl file from the
benchmark part used in the rapid prototype journal entry titled
"Benchmarking for comparative evaluation of RP systems and processes"
by M.
Mahesh, Y.S. Wong, J.Y.H. Fuh, and H.T. Loh, found in Volume 10 Number
2
dated 2004, pp. 123-135. Does anyone have a copy of this model file
they
can send to me? I'd appreciate any help you can provide.

I only have a cursory knowledge of RP processes but I'm trying to ramp
up
fast. I'd appreciate any information that can be provided to me.

Thank you,

Jim Good
