If you thought 3D printing was cool . . .

4D is now looking for things to do!

A student in New Zealand has developed multi-material organic like printed objects that can interact with their environment. Eventually biological models, with bones, a vascular system, soft tissues etc, of body parts may be made - that surgeons can use for practicing experimental sugical techniques.

Bringing objects to life with 4D multi-material printing
Research by Victoria University of Wellington student Nicole Hone is bringing 3D prints to life and drawing attention from international industry and design bodies.

The BBC prog, 'Click', which also includes news of the "Atomic Radio" where I heard of this:

Later: relistening to the "Atomic Clock" piece it is more of an "atomic aerial" ,  a "capsule" of laser excited atoms that react to radio waves in duch a way that they modulate the laser light in a detectable way. Sounds like it is mainly microwave, gigaHertz, frequencies but it has a broad frequency response within that range. Early days yet, not hi-fi.

It would be cool if we could print structures for bones, veins, lungs, etc. Might make growing organs an easier task.

Have you seen the 3D house printers? They look fascinating too...
