Nice credits for Sigma Labs and 3DSIM...

Also key to the reproducibility of the MetalFAB1 3D printing process are two partnerships. Sigma Labs, a spin-off of Los Alamos National Lab in New Mexico, has commercialized an in-process monitoring tool called PrintRite3D, which combines sensors with software to provide real-time feedback on the 3D printing process in order to analyze the variables that yield an optimal part. About this partnership, Kersten remarked, “We monitor the melt pool through a solution developed by our partner Sigma Labs, because they’re experts in that field. There’s no reason why we would reinvent the wheel if it’s already been invented by someone else.”

Additive Industries has also partnered with 3DSIM, a spin-off of the University of Louisville in Kentucky. 3DSIM has developed an entirely new print preview platform called exaSIM, which takes into account almost every variable imaginable that goes into the 3D printing process and predicts the outcome of the print. These variables include the makeup of a given material, the effect of the energy source on the temperature of the build chamber and the melt pool, the physical interactions between that energy and the material, and much more. The ideal result is the ability to generate an accurate print preview.

“We are also partnering with 3DSIM to integrate their simulation software into our workflow because we’re strong believers that you should simulate a job before you print it. That will increase your yield and, therefore, your productivity,” Kersten said.

Here's something that sounds a bit more positive, from same time frame.... http://www.engineering.com/3DPrinting/3DPrintingArticles/ArticleID/12251/Additive-Industries-Evolves-Metal-3D-Printing-at-RAPID-2016.aspx

Hoping for a nice upward trend! fingers crossed.
