As we promised some posts ago, today we are going to talk about 3D printing of artificial organs.
Princeton Univer¬sity and Johns Hopkins University had printed an ear from different materials: a hydrogel to form an ear-shaped scaffold, cells that will grow to form cartilage, and silver nanoparticles to form an  antena.Impresión órganos

Actually, the principal activity is the bones printing from polymeric material or from metal that adapts perfectly to the before bone or even they have better properties than typical titanium in bone re-growing. Another of the most interesting activities it is the printing of live cells to generate new tissues. Researchers still consider complicated to print whole organs such as kidneys and livers because of the structural complexity but they believe it is feasible to print tissue patches to repair damaged zones.
