makes sense to me

A 3-D shape that moves in time when some kind of stimulus is applied.  The term used "4D printing" makes sense to me. 

The use of the term "self-assembling" is stretching things a bit.  Folding into a box isn't quite an assembly to my mind.  You need to connect at least two objects together to define an assembly.

It's a neat idea.  Let's see what they can do with it.  You could remove some assembly steps with this idea I suppose?

Mydesign, 4D printing is defined as 3D printing plus another dimension--time, which is commonly known as the fourth dimension. By "time" this usually means 3D printing an object that, because of characteristics of its material, then changes its shape over time. Personally, I think the designation is silly, which is why I didn't use it when reporting on Skylar Tibbits' work here:
At the time of my report, his TED talk wasn't available, but you might want to check it out--we give a link in today's blog.
The technology I'm reporting on here is using "4D printing" techniques to create self-assembling objects.

"Researchers at the University of Colorado Boulder have combined 3D printing on the Objet Connex multi-material 3D printer with making shape-memory composites, calling that process 4D printing."

Ann, I won't think that's a 4D printing and it may need some clarity about 4D and 5D printing technology. Printing a 3D image of 3D object won't be defined as 4D printing. I heard that adding another dimension to 3D printing can lead to a 4D printing.
