3D printing breakthrough could change healthcare

A new 3D printing technique developed at Carnegie Mellon will allow the printing of soft living tissue like that of our own organs. The most amazing part is that Carnegie Mellon has done this with off-the-shelf 3D printers that cost about $1,000. Up until now, 3D printing was mostly done using rigid materials like plastics, resins, and metal. Until this process, 3D printing of soft tissue required special artificial frameworks or lattices to hold together the organs. Otherwise, if you try to print softer materials in air, they cannot support their own weight as you add layers of material.
