Researchers have used metamaterials and 3-D printing to develop a novel lens that works with terahertz frequencies. Not only does it have better imaging capabilities than common lenses, but it opens the door for more advances in the mysterious realm of the terahertz.
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.
