When people say 3D printing will change the world, it's like saying the wheel or sliced bread changed the world. They are enabling technologies. A wheel is useless with out a road. Slice bread gets stale with out the airtight plastic bag and the means to deliver it quickly. 3D printing is the vector for allowing new and novel materials, goods and applications to come forward. I think the real key is the design step that takes advantage of the additive manufacturing process. I was at a local 3d printing meeting a few months ago and it really hit me. The printers are the easy part, they do what they are told. The key is in the design. Which leads to all kinds of intellectual property issues that makes the song/napster issue seem simple.
Maybe not the 40W fazer, but an interesting step forward with a gun design from the past...

It's that simple.
