Ray,
This is a great idea !
One could compare the following four ways of RFQ:
1. Send 2D drawings on paper
2. Send 2D drawings and isometric views on paper
3. Send 2D drawings and isometric views on paper, together with 3D
volume file on floppy (VRML format)
4. Send 2D drawings and isometric views on paper, together with physical
rapid prototype part.
Then, one could request tools for four different parts by all four
methods per toolmaker, so each toolmaker gets four different requests.
naturally, you must permutate the parts to wipe out the effect of
geometrical complexity differences.
The parts should be complex with undercuts, curved parting lines, small
features, ...(connectors, hehehe), but not equal
Examples: connector, mobile phone, pump housing, electric mirror
housing.
Who likes to do that ???
Any researchers out there ?

Clara,
I think there is a project waiting on the simple application of Rapid
Prototyping as a visualization tool for molders/ mold makers.
Visualization
models are cheap now with the introduction of machines like 3D Systems
Actua. Ford and others have done studies showing that quotes are 10-15%
less when a rapid prototype is sent along with the RFQ. And when an
order
has been taken for the tool, make a Rapid Prototype for the tool
designer.
A 3D model will result in both instances in a faster understanding of
the
part geometry and will result in less errors being made in the tool
construction. Translation: dollar savings in the RFQ stage, and time
and
dollar savings in the actual mold building.
Yet few molders/ mold makers do this as a standard part of the business
process. A great project would be to document the savings and write an
article for a plastic's magazine!
