In my opinion that is a poorly researched article based solely on rumor. Make sure you read the comments at the end of that article.

While attending Rapid 2014, the largest 3-D printing convention in North America, a prevailing rumor was that U.K-based Renishaw, a precision measurement company turned 3-D printing company, would introduce a successor to its flagship AM 250 laser melting printer with the ability to analyze each layer of the build process.

Although I wasn't able to confirm this rumor, quality assurance technology of this caliber would have game-changing implications for 3-D adoption rates in manufacturing settings, because an engineer would have the data from the entire build process, one layer at a time, to determine if any layer of the process had issues. Bear in mind, the inside of a metal 3-D printing chamber involves high energy lasers, residual heat, and flying metal particles, meaning this undertaking isn't going to be cakewalk for Renishaw, General Electric, or any company to introduce this level of needed quality control.

Also do a search for Renishaw & in-process quality assurance and see what you get.
