The usual steps sent it to the 3D printer to be produced at 0.2 mm resolution. It only took 49 hours to print at full-size. This brain was printed for fun, but we’ve seen other 3D printed brain ...

Key cells in the brain, neurons, form networks by exchanging ... nanopillar arrays using two-photon polymerization, a 3D laser-assisted printing technique with nanoscale precision.

3D bioprinting enables researchers to select cell types and spatial ... Zhang anticipated random neural connections from artificial printing, but the tissues behaved just like they do in the brain.
