RE: 3D fossil printing



Around 2000, we did two, complete, 1/6 scale miniature skeletons of the
Smithsonian Triceratops using stereolithography. Then Pete and Steve cast
the prototype bones and made casts for various other uses. They were
incredibly handy for planning the mount and for doing functional morphology.
They should all be in the SI collections. We also did a 7 foot long skull
copy of the 6 foot original skull using about 36 large blocks of
stereolithography fused together so we could have a proper-sized head for
the new mount. Pete and Steve then cast that. The shape was fine. Finally,
we cut a couple beautiful copies of full-sized bones using a CNC system,
including the left humerus as a mirror of the nice right. You can read a
description in the technology chapter in the new Complete Dnosaur edition of
the project. All in all it fixed the old mount right up.

There is a sculpture of the skeleton in the original, historical pose in the
horned-dinosaur exhibit using the 1/6 scale cast bones and it is fabulous.
Everyone who sees it wants one, including me.

She's not used to that yet?

Anyway - how about a microraptor?
