If you get it printed in PLA - the low level plastic can be dissolved
out and anything left burnt in mold generation. Or if you are into
green sand directly Make the part.

The Ring industry is into this exact function. They make blanks with
details that are refined and polished up pretty.

Last evening I went to a beginners class on 3D printing. The class was using a program by Autodesk called " 123D Design " to create files for 3D printing. Looks like a pretty good program especially considering that the program is free.

The local library will print a 3D object for free as long as it does not take more than 5 hours to print and you accept whatever color they are using.

Looks like it would be easy to print up a pattern to use in casting parts.

If you search on 123D Design , you will find some additional programs to use for things as scanning an object and creating a duplicate by 3 D printing.

So is anyone doing anything with 3D printing?
