Gautham,
One comment about your process. If you want the Z-axis (perpendicular to the
slices) to be the proper scale relative to the X & Y, then the size of your
projection relative to the original, the foam thickness, and the slice
thickness chosen in QuickSlice must all be considered. I think you said you
were doing a big tooth, and you would end up with one that is too tall or
short otherwise.
Regards,
...Derek

marshall,
Ok- thermocoal is no magic material. Its called styrofoam
here.
Thermocoal is what we call it in the country where I am from.
Here's a brief review of the process of using styrofoam sheets to
build scaled
prototypes:
The process is a simple one, but time consuming . All it
would neeed
is a slicing software, a overhead projector, slabs of styrofoam &
some
patientce. Once the part is sliced, these students used a projector
to project
each slice on a wall. THey adjusted the distance of the projecttor
to the wall
to scale the slices up to the scale they wanted. Then they placed a
slab of
styrofoam on the projection of each slice , outlined the contours
with a pen ,
cut against the outline with a hot knife & then glued the individual
slices
together to get the prototype. The thickness of the styrofoam slabs
or sheets
determine the layer thickness.
Regards,
gautham
