customers requiring high-quality AM metal products production. The USPTO has now allowed four
patents pertaining to Sigma Lab’s PrintRite3D platform, representing a wide degree of innovation and
distinguishing us as a leader in this space. Additionally, there are eighteen more patents-pending in
Mr. Rice concluded, “Sigma’s patent portfolio, our newly launched platform, and our recently signed
