RP in production materials based on physical model

I only recently joined this listserv, and am
impressed with the range of issues that you all
deal with! This is very informative.

I am currently working with a European firm that
needs to improve their RP capabilities. They have
specific goals to develop an in-house capability
to produce prototype parts on a dedicated
injection molding machine less than a week from
when they finalize a design. Ideally, they would
like to get more than 100 parts form the mold, but
as few as 15 can be acceptable. Cycle times are
not terribly important, and automatic ejection is
unneeded at this point in time. Their tolerances
are not terribly tight, .01".

Production materials include:


The real catch is that they create the original
models by hand with a technique called Mosaic.
They are currently not willing to move to a
digital design process. Reverse engineering the
parts, may be acceptable, but costs and time may
be a limiting factor. The mosaic part can
withstand temperatures of 55-60 deg C. I do not
currently have a value for the pressure that the
mosaic parts can withstand.

Does anybody have any ideas about how this RP work
can be accomplished so that they can reach their

Thank you in advance for your help!
