What have you printed for use? I'm in the process of starting to 3D print

I find that fascinating and have been studying it intensely. There are other plastics imbeded with fibers which make the prints stronger. Someone came up with a special cartridge that takes all the force of the explosion and spares the printed gun from a beating. I think the inventor calls it the .416 Atlas?. It's an interesting concept and is on Youtube.
