3D Printer makes working tools with moving parts

We’re not quite to the point where we can push a button and say, “Tea. Earl Grey. Hot.” Then again, we may not be as far off as most would believe.
The amazing technology behind the 3D printer is mind-blowing. From scanning and understanding every aspect of a tool, even moving parts, all the way to the actual “printing” process are things that are clearly out of a science fiction book and not reality, and yet there it is. Watch the video. Be amazed. Dream about the future.
It is a very interesting discovery that`s for sure.
I think it will develop over time.
Well they say the old stuff works best.
That really is old school ..surely they can do better than that?
