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
