July 2017 – Sigma Labs announced the June 30, 2016 publication of its U.S. Patent Application No. US 2016/0185048; Multi-Sensor Quality Inference and Control for Additive Manufacturing Processes. This patent application is related to real-time quality analysis during AM processes and the characterization of material properties using acoustic signals emitted during AM which can be used in addition to optical signals to simplify the qualification of printed parts. 

"This has been a strong quarter for Sigma Labs in which Sigma Labs’ technical team has placed PrintRite3D® INSPECT firmly in step with a market that we believe is pushing towards production," said John Rice, interim CEO of Sigma Labs. “Our newly released PrintRite3D® INSPECT™ In-Process Quality Assurance Software Version 3.0 with 3D-thermal mapping and imaging tools is a major step forward for Sigma Labs that positions us at the forefront of the AM market with capabilities that facilitate enhanced real time AM manufacturing.”

Third Quarter Ended September 30, 2017 Financial Results

Our General and Administrative Expenses for the three and nine months ended September 30, 2017, were $576,855 and $1,814,843, respectively, as compared to $437,870 and $1,314,055 for the same periods in 2016. Our payroll expenses for the three and nine months ended September 30, 2017 were $295,890 and $973,172, respectively, as compared to $259,011 and $727,494 for the same periods in 2016. Our expenses relating to stock-based compensation for the three and nine months ended September 30, 2017 were $199,225 and $505,630, respectively, as compared to $105,641 and $236,554, respectively, for the same periods in 2016. Our research and development expenses for the three and nine months ended September 30, 2017 were $57,947 and $225,562, respectively, as compared to $37,526 and $88,504 for the same periods in 2016.

General and Administrative Expenses principally include internal operating and sales expenses and outside service fees, the largest component of which consists of services in connection with our obligations as an SEC reporting company. The increase in General and Administrative expenses for the three and nine months ended September 30, 2017 as compared to the same period in 2016 is principally the result of fees relating to and as a consequence of our February 2017 public offering that resulted in net proceeds of approximately $5,225,650, fees incurred in connection with investing in strategic partners, the increase in interest and finance costs on the $1,000,000 note originated in October of 2016, along with the continued development of our IPQA®-enabled PrintRite3D® technologies and our related efforts to expand our services. The increase in payroll expenses for the three and nine months ended September 30, 2017 as compared to the same periods in 2016 is principally the result of our hiring of additional software development staff to assist in acceleration of our IPQA®-enabled PrintRite3D® technologies and 2017 increases in administrative salaries. The increase in research and development expenses for the three and nine months ended September 30, 2017 as compared to the same periods in 2016 is principally the result of increased contract consulting combined with software and hardware upgrades required for the continued development and improvement of our software and technology. The increase in stock-based compensation costs is due to the fact that the majority of stock options were granted after September 30, 2016, thus more stock option vesting occurred in each quarter of 2017 than in the same periods of 2016.

Our General and Administrative expenses are expected to continue to increase as we seek further commercialization of our IPQA®-enabled PrintRite3D® technologies through increased marketing and sales efforts. Similarly, we anticipate that our payroll and non-cash compensation expenses will continue to increase as we engage more employees and other service providers to support our efforts to grow our business.

Our net loss for the three and nine months ended September 30, 2017 increased over each of the prior year comparative periods and totaled $1,116,910 and $3,049,616, respectively, as compared to $719,320 and $1,931,833 for the same periods in 2016. This increase in net loss was attributable to a decrease in revenue and an increase in expenses as noted above.

As of September 30, 2017, we had $2,691,487 in cash and had a working capital surplus of $2,482,056, as compared with $398,391 in cash and a working capital surplus of $110,799 as of December 31, 2016.
