The interesting thing is:
I work 6 month in China and I have more revenue than Sigma Labs worldwide, so what is wrong with the company?

EWI has been evaluating our software in association with NIST.

Look for the asterisks below regarding IPQA

Separately, Sigma Labs received an initial contract from the EWI as part of the previously-announced grant from the U.S. Department of Commerce's National Institute of Standards and Technology (NIST) for the development of in-process sensing and monitoring capabilities to ensure consistent quality in 3D printing. The grant, worth $5 million in total, was awarded to a group of universities, laboratories, and companies in the field of additive manufacturing; Sigma Labs' contract will evaluate the Company's PrintRite3D® technology for monitoring and control applications.

Nondestructive Post-process Evaluation (NDE) of AM Parts investigates four common NDE techniques – ultrasound (UT), eddy current (ET), pulsed thermography (PdTh), and computed tomography (CT) for examination of laser powder bed fusion (L-PBF) Inconel 625 (In625) specimens with pre-designed imbedded defects for technology qualification.

AM Powder Recycling and Reconditioning for L-PBF focuses on two aspects of powder reconditioning: 1) using Tekna’s plasma induction system to improve morphology and evaluate effects on chemical composition of the powder, and 2) blending used and virgin powder in varying proportions to evaluate its effect on powder reconditioning.

In-process Monitoring and Rectification of Defects in L-PBF focuses on the development of methods for in-process detection and rectification of open-to-surface defects in L-PBF processes. ***EWI will take advantage of their previous work that consists of over three years and over 2.5 million dollars of government and internal funding.***

High-strength Aluminum Alloys for L-PBF. A project was initiated to develop laser-based powder bed fusion process parameters for high-strength aluminum alloys. The AMC will execute a test program to evaluate and develop build parameters for aluminum alloy materials with properties equivalent to 7000 series aluminum alloys.
