Living 3D Printer Filament
This is more than a printing filament hack — closer to bleeding edge bio-engineering — but we can’t help but be fascinated by the prospect of 3D printing with filament that’s alive on a cellular level.
The team from MIT led by [Xuanhe Zhao] and [Timothy Lu] have programmed bacteria cells to respond to specific compounds. To demonstrate, they printed a temporary tattoo of a tree formed of the sturdy bacteria and a hydrogel ‘ink’ loaded with nutrients, that lights up over a few hours when adhered to skin swabbed with these specific stimuli.
So far, the team has been …read more
