Not printing tissues, or functional gradients, I know.
Here are some links below, but I actually think that the authors themselves font see the potential it has. Although granted, I like it because of the potential for *grassroots* technological development, like the reprap. They are thinking in a very different context.
A lot of these documents are super old, yet no progress has been delivered... If this potential is to be delivered there probably has to be a project to get it going like the reprap did for filament deposition manufacturing.
Btw, the executive summary is that you produce a highly accurate mold of almost any desired shape, of a destroyable mold material, then fill and destroy the mold material.
There are a few limitations on geometry, but less even than powder bed laser sintering. Like tubular objects or hollow tanks have to have some holes in the side, which you might have to patch up later. And minimum feature sizes, but they could be five thousands of an inch easily.
When you are actually involved in manufacturing, you see what small fries that is, in comparison...

The stuff below I c cannot remove, my browser is malfunctioning.
I don't think we will ever or at least in the near future, be able to get a combination of tight tolerances like utc-5, good surface finish, normal engineering materials with the range of properties we need, no limits on general geometry, and speed, our of any of the printing processes currently under development in the public sphere.

Can't decipher the above sentence.
"no limits on general geometry, and speed, " Can first comma be left out? Probably.
then this shows up as last element in a list:
"our of any of the printing processes currently under development in the public sphere."
What is that?
"under development in the public sphere" That suggests fiction of the fantasy category to me.
