PrintRite3D uses Multi-Sensor Technology for 3D Printer Control
http://jjsigmalabsblog.blogspot.com/2014/02/p...and_7.html
PrintRite3D incorporates acoustic, thermal, and optical data for the closed-loop control of 3D printers.
Here are the specifications of PrintRite3D showing the use of acoustic, thermal, and optical monitors:

Here is an article stating how PrintRite3D uses both acoustic and optical sensors:

Recall that acoustic emissions is a reliable signal that can delineate metallurgical, thermal, and mechanical properties:

There is a 228 page study written by Hongping Gu titled, "Real-time Monitoring and Adaptive Control of CO2 Laser Beam Welding" that showed the combination of acoustic emission & optical monitoring having 98% accuracy(page 201).

In this study, Sigma Labs used a high speed video recorder for their IPQA demonstration for the Air Force:

Note: Acoustic power spectrum is the ease at which signals are detected. The study showed 100% detection ability in 62 sample runs .
PrintRite3D is a complete system that incorporates acoustic, thermal, and high resolution optical sensors for quality assurance. The AM process has no system to monitor the manufacturing process and correct 3D printers. By ensuring the printing process, the need for timely post-process inspection will be amortized by Sigma Lab's IPQA technology.

Sigma Labs also studied acoustic emissions for weld quality classification and their detection rate was 100%:

Sigma Labs released news of patent filing for a unique sensor that will assist both process development and quality assurance on 03/25/14:
Sigma Labs is the only company to use multi-sensor technology to ensure quality. They will continue to conduct research, and possibly with their agreement with Los Alamos National Laboratory, develop active sensors for the monitor and control of 3D printers:
