RE: [rp-ml] Ceramic structures using RP

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.

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
