Researchers at North Carolina State University reported the discovery of a distinct form of solid carbon they estimate is about 10 percent harder than diamond and could play an important role in machining. They also claim to have developed a relatively inexpensive technique for producing the substance, called Q-carbon, at room temperature and ambient atmospheric pressure.

TruPrint 1000 LMF 3D Printer

The new TruPrint 1000 LMF 3D printer works like a selective laser melting 3D printer, using a powder bed process to build 3D parts by laying down a thin layer of metal powder materials onto the build surface while a 200-watt laser fuses the layer of powder along the contour of the part being printed.
