Normally, Fang explains, stiffness and strength declines with the density of any material; that’s why when bone density decreases, fractures become more likely. But using the right mathematically determined structures to distribute and direct the loads — the way the arrangement of vertical, horizontal, and diagonal beams do in a structure like the Eiffel Tower — the lighter structure can maintain its strength.

Additive manufacturing—the industrial version of 3-D printing—is already used to make some niche items, such as medical implants, and to produce plastic prototypes for engineers and designers. But the decision to mass-produce a critical metal-alloy part to be used in thousands of jet engines is a significant milestone for the technology. And while 3-D printing for consumers and small entrepreneurs has received a great deal of publicity, it is in manufacturing where the technology could have its most significant commercial impact

“Terrorists can make these guns and do some horrible things to an individual and then walk away scott-free, and that is something that is really dangerous,” said Yee.

Working under a grant from the Arts and Humanities Research Council (AHRC), Hoskins and Research Fellow David Huson have been developing a 3D ceramic printing process that can build very finely detailed, complex structures to industrial specifications and standards. The process works by depositing a layer of wet ceramic material layer by layer. As each layer is printed, the printer table drops, a layer of powder is deposited to support the object, and the process repeats.
via Ancient Egyptian faience may be key to printing 3D ceramics.
It isn’t actually a ceramic, but rather a paste made of quartz or sand, calcite lime and a mixture of alkalis. Because of this, it can be applied directly to wet clay. When the pottery is fired, the paste turns into a brilliant blue-green glaze reminiscent of lapis lazuli, which the Egyptians used faience as a substitute for.
Competing in the prestigious Formula Student 2012 challenge, a 16-man strong team of next-generation engineers from Group T have unveiled the world’s first race car created in great part through 3D Printing:
