3D Printing Organs
So there is this new emerging technology of 3D printing an organ.It prints an organ through an inkjet introducing a mixture of bio gell,human cells and proteins onto a tray.It can certainly print any human organ,capillaries and small veins but is not launched to public as the way it is done is too complicated and hella expensive.A bio company even transplanted a 3D printed liver which worked
well for 2 months.It is far from mass usage right now but it might be out in Walmart a decade later.
