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.
Engineers are expanding the already impressive portfolio of 3D printing technology to include electrical components, such as resistors, inductors, capacitors and integrated wireless electrical sensing systems. They have put the new technology to the test by printing a wireless 'smart cap' for a milk carton that detected signs of spoilage using embedded sensors.
The use of 3D printers has the potential to revolutionize the way food is manufactured within the next 10 to 20 years, impacting everything from how military personnel get food on the battlefield to how long it takes to get a meal from the computer to your table.
