This is what brain synapses look like in 3D

Many know that brains are inherently complex things; there are trillions of synapses converting chemical and electrical signals in a human mind. However, did you know that even those synapses are very complex? If not, it should be perfectly clear now. German scientists have used a mix of extremely high-resolution microscopes (both electron and fluorescent), mass spectrometry and protein detection to create a super-detailed 3D map of a synapse in a rat's brain. It's almost like a miniscule city -- those dots you see represent 300,000 proteins, and only a tiny portion (the glowing red patch at the bottom) is transmitting chemicals.

So cool!! Can we 3-d print it?

".... those dots you see represent 300,000 proteins".  Proteins are even more complex than genes.

But perhaps one day soon.

I guess we could start by 3-d printing protein models?
