Some of you may recall a post I did over a year ago about 3d printing.
(For those that missed it and don't want to go to the link, 3d printing is way of printing an object, like a wrench, or motorcycle, that is fully functional.
The link to the former post has a video that will show you that actually happening.)
It was such shocking idea at the time.
Well, saddle up for a new shock:
Technology has marched on.
Now there is 4d printing.
What does that mean?
It means the object prints up, and then assembles itself.
