Printing a chocolate heart is easy enough, but how about an actual organ. There are folks working on it, but it turns out those veins of yours aren't exactly a breeze to replicate. Researchers at the University of Pennsylvania and MIT may have found a semi-sweet solution - dissolving a sugar lattice in a batch of living Jell-O. The research team uses a RepRap 3D printer and a custom extruder head to print a filament network composed of sucrose, glucose and dextran which is later encased in a bio-gel containing living cells. Once the confectionery paths are dissolved, they leave a network of artery-like channels in their void.
