"The process is called volumetric printing. Rotating images of an object are beamed through a conventional video projector. The light is focused on a slowly rotating cylinder of gooey resin containing plastic molecules with a light sensitive-activator.

As light accumulates in desired areas, the gel begins to harden and, in about 30 seconds, a solid 3D object is created–not in layers, but all at once.

...researchers are even imagining ways to use volumetric printing to arrange human cells into living organs, such as livers or kidneys.

“I think it might happen in the next decade that we may actually see a functional organ ready to be implanted or transplanted,” Heidari said.

...I think what’s really important about it in terms of transitioning to a commercial product is that the hardware associated with it is very inexpensive,” said Dr. Chris Spadaccini from Lawrence Livermore National Laboratory.

Now that the concept has been proven, the next challenge will be to increase the size, complexity and quality of objects being manufactured. That should open the door to all kinds of commercial uses."

Exciting stuff.
