In a lab I work in now, we make buoys for sensing stuff in rivers, and
we coat the PCBs with a silicone spray to avoid water or salt
failure.... NASA could have something different, but it also seems
like a pretty solid method. I'll get the name of the spray tonight or
tomorrow.

I guess it depends how well the silicone spray cures... would not be
hard to find out!

That it began beating is quite hard for me to believe. The heart can't
be made of homogeneous cell types, can it? I mean, muscle fibers vs
ventricle walls must be expressing different proteins... to me organs
are things that must start out as a stem cell (or group of them),
differentiate, and expand into the final shape
Do you have a citation for that "heart printing"?

I recall this as well. Mind, he said beating, not that it was pumping
anything. Heart cells have a sympathetic mechanism that can, in some
circumstances, cause them to beat even without a signal from the
nervous system.

anything. Heart cells have a sympathetic mechanism that can, in some
circumstances, cause them to beat even without a signal from the
nervous system.
Thinking about this, the cells may be only providing structural
support? For a heart to beat on its own, you would need the pace maker
cells [SA and AV nodes] and the nerves. I think the pumping may be due
to artificial means of moving fluid through the chambers. It's not too
clear from the video. Any ideas?

This system uses a computer controlled four-axis positioning table to
"print" intricate bio-architectural constructions out of moss and
seeds. Suspended in a clear gel growth medium, the moss continues to
grow and the seeds sprout. The algorithmically-generated patterns
drawn by the system are based on the Eden growth model and leverage
mathematical representations of both urban growth and cellular growth,
thereby connecting the concept of city with the concept of the
organism. This project is working to make concrete the idea of dynamic
and fluid computer space altering the expression and formation of a
living and growing biological material, via its collaboration with an
engineering mechanism. -- from Allison's site

Don't know where you are but in every country in the free world that I know of they are perfectly legal.
As far as sterilization... Why not just run it like a flow hood or sterile transfer room. You have a UV light and mostly leave it on all day except for when you're actually using it. You can get UV bulbs of just about any size, with many of them in the $10-15 range. I got one from 1000bulbs.com awhile back for about that price. It might be hard on the plastic or eventually damage any optical sensors in the system, but the actual printer is pretty cheap. I could get pallets of random used inkjets for basically nothing at surplus. In lots of places you actually have to pay to have them recycled, which a lot of people do when they find out it's almost cheaper to buy a new one rather than replace the cartridges.
