It may be worth mentioning the context of the "pattern" statement in the material guide, since most people are unaware of the applications for 3D printing in casting.
Thank you for posting the pictures, Abby. It's nice to see details of other people attempts so we aren't needlessly replicating work. I spoke with an Objet representative about using their materials (the Detail materials) for investment casting and he said some users had done it successfully, but that some ash would be left (it is acrylic plastic) so you can't expect perfection. Still, it might be worth trying Transparent Detail for these projects.
Edit: Also, hollowing out the models would leave far less material to burn away, and that could make all the difference.
