A team of NASA technologists has begun investigating the use of a technique called aerosol jet printing or direct-write manufacturing to produce new detector assemblies that are not possible with traditional assembly processes.
With findings that could have been taken from the pages of a spy novel, researchers have demonstrated that they can purloin intellectual property by recording and processing sounds emitted by a 3-D printer.
Researchers have designed and tested an open-source system that uses a laser to melt powdered plastics and biomaterials into intricate 3-D designs. The OpenSLS selective laser sintering system costs about 40 times less than its commercial counterparts and allows researchers to work with their own specialized powdered materials.
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.
