Sigma Labs, Inc. (OTCMKTS:SGLB, SGLB message board) went through a rather rough patch over the past few months, with the share price slipping steadily to hit new 52-week lows in mid-February. It seems now Sigma is starting to find its footing again. The company published a press release on Monday morning that stirred up heavier volume and eventually – price action on Tuesday. Yesterday SGLB closed 27% up on its heaviest daily volume for the past 6 months.

Sigma announced that the company will conduct a launch event on April 14, to present to the world its M290 additive 3D printer for metal. The printer will contain the flagship product that got SGLB in the 3D printing spotlight in the first place – the company's proprietary PrintRite3D technology for in-process quality assurance. Representatives from the industry and government are to attend the launch event.

Sigma ran hot in early 2014 as this was the year when PrintRite was supposed to finally get commercialized and start generating sizable revenues for the company. This had not happened as of the last available financial report from SGLB covering Q3 of 2014.

Sigma's PrintRite was and still is being tested by major names in the aerospace industry but the lack of any finality regarding revenue-generating contracts could be one of the reasons investors started turning the company a cold shoulder, despite projections of $200 thousand in Q4 revenues ahead of the annual report. There was also the matter with commercialization being once again postponed.

It seems with the launch of the M290 printer with PrintRite onboard Sigma is finally pulling through and will get another shot at glory if it manages to maintain yesterday's momentum a little further. Today the ticker is trading on far calmer volumes but is another 7% up in the early session.
