RE: [rp-ml] Ceramic structures using RP

Those would be considered more composite materials than ceramic. Ideally,
ceramic denotes a very high temp application. Glass filled nylon, some of
the SLA composites, and FDM have some high temp applications. I guess it
would depend on the requirements.

  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
