A team of researchers has developed a way to use 3-D printers to create objects capable of expanding dramatically that could someday be used in applications ranging from space missions to biomedical devices.
Using the principles behind the formation of sandcastles from wet sand, researchers have achieved 3-D printing of flexible and porous silicone rubber structures through a new technique that combines water with solid and liquid forms of silicone into a pasty ink that can be fed through a 3-D printer.
A group of researchers has discovered ways for manufacturers to turn the tables on thieves by deliberately embedding hidden flaws in CAD files to thwart intellectual property theft. In a new study, they show how certain intentionally induced defects can disappear when the part is printed under a very specific set of conditions.
For the millions of people every year who have or need medical devices implanted, a new advancement in 3D printing technology promises significantly quicker implantation of devices that are stronger, less expensive, more flexible and more comfortable than anything currently available.
As a consequence of the properties of glass, such as transparency, thermal stability and resistance to acids, the use of this material in 3D-printing opens up manifold new applications in production and research, such as optics, data transmission, and biotechnology.
