This was printed at 350% original scale in PLA material on SeeMeCNC RoStock MAX V2.0 custom 3D printer. We sanded and prepped the bullet with Rustolium primer followed by 2 coats of high gloss gold and silver to make it look realistic. We then used a 2 part epoxy to bond the bullet to the shell since we didn't want it removable anymore.
There will be a video on this at http://barnnerd.com in the near future!
This was printed at 350% scale to make a massive bullet. I use a SeeMeCNC RoStock MAX v2.0 which allowed me to print a very tall item.
