Sigma Labs is unique -- here is the article that proves it
Anyone reading this likely has heard the basics of the Sigma Labs PrintRite3D story. That it is based on patented software and hardware (PrintRite3D) which is unique in that it provides In-Process Quality Assurance (IPQA) in a closed-loop fashion so that 3D printers can correct for errors while printing is underway, i.e., not destructively after the product is already done. As you can well imagine this not only saves huge amounts of money, but huge amounts of time as well.
Until I read J.J. Smith's blog article "In-Process Monitoring Requires Understanding of Material Properties" today (Feb. 18, 2014) I didn't realize that not only is PrintRite3D unique but it is extremely difficult for any printer OEM or other competitor to even replicate its capabilities if they had a machine to copy. J.J Smith does a great job of collecting the detailed quotes from aerospace manufacturer's using IPQA today to explain why PrintRite3D will not work without Sigma Labs people being involved. B6 Sigma is their consulting arm and the website where you will find the descriptions of each of the PrintRite3D modules. Because PrintRite3D requires detailed data interpretation that the equipment can not do on its own, it can not operate without expert users who have the scientific expertise Sigma Labs people received when they developed this technology at the Los Alamos National Laboratory's Advance Welding Technology Research Group that Mark Cola led before starting SGLB.
J.J. Smith has further quotes from industry executives explaining how they can not do without a close-loop IPQA if they are going to meet their needs.
Google J.J. Smith's blog and find this article, I can't copy a link here. It is worth a read by anyone deciding to invest in SGLB. Thank you J.J. for your great research!
