Re: 3D fossil printing
as long as you can get an stl (or even an obj) 3d file, you can just go to a
site like www.shapeways.com for 3d printing - you upload it and they send it
back - the price depends on materials and the volume of material used, but
typicaly it's about $1 per cubic cm. the price does mount up quickly, but
it's cheap emough to do a test for yourself if you're curious (I've only
ever used it for arty stuff, never fossils btw).
The main drawback is that while surface detail comes out well, there are
limits to "wall and gap thickness" - so if you've got knobbly bits on your
model it will work OK, but if you've got thin bones or struts or objects
close to each other, you'll need to upsize so that the thinnest is more than
1mm (I think it's 1mm) or risk that detail not appearing correctly. And of
course, upsizing increases cost.

This sounds very cool. I'd love to have some early homninid printings.
I wonder how detailed this can get

SERGIO AZEVEDO was prospecting at an old railroad site in So Paulo state,
Brazil, when he discovered the fossilised bones of an unknown animal.
"Many times when you find a fossil in the field it's impossible to
determine how much of the ancient animal you have," he says. "Sometimes
you have just part of a bone or a tooth." Azevedo has a solution to this
perennial problem, which also acts as a safety net in case a stray hammer
blow destroys an ancient fossil during excavation. Just scan it and print
His team at the National Museum of Brazil in Rio used a portable CT
scanner to determine the orientation of the specimen in the ground, then
they cut out a large section of rock to take back to the lab. There the
encased fossil was probed using a more powerful scanner - and a 3D
printed out in resin.
