Researchers have found a way to print composite material by making a relatively simple addition to a cheap, off-the-shelf 3D printer. The breakthrough was based on the simple idea of printing using a liquid polymer mixed with millions of tiny fibres.
Using sugar, silicone and a 3-D printer, a team of bioengineers and surgeons have created an implant with an intricate network of blood vessels that points toward a future of growing replacement tissues and organs for transplantation.
The researchers combined silk proteins, which are biocompatible, and glycerol, a non-toxic sugar alcohol commonly found in food and pharmaceutical products. The resulting ink was clear, flexible, and stable in water.
A team of researchers has developed a first-of-its-kind, 3D-printed guide that helps regrow both the sensory and motor functions of complex nerves after injury. The groundbreaking research has the potential to help more than 200,000 people annually who experience nerve injuries or disease.
A bench-top brain that accurately reflects actual brain tissue would be significant for researching not only the effect of drugs, but brain disorders like schizophrenia, and degenerative brain disease. Researchers have made progress in this area, 3-D printing a six-layered structure like brain tissue, in which cells are accurately placed and remain in their designated layer.
