3D printing new artificial or totally regenerated organs will be a key medical technology in living forever. Manufacturing completely personalised metal implants is already here that perfectly fit a patient's anatomy. And bioprinting new body parts, using stem cells and bioinks, that incorporate different cells and blood vessels are being developed all around the world.

3D printers can also create personalised drugs that can combine multiple active ingredients in a single pill, with a physical structure designed to release the contents at a rate ideal for each patient.

Other uses in healthcare include personalised prosthetics, manufacturing of sterile surgical tools at a reduced cost, and printing models of organs and bones to help surgeons prepare for complex surgery.
