Honestly, I don't know.  I do not follow the dail

Honestly, I don't know.  I do not follow the daily selling and buying volume.  Even if the shares become available I see them as opportunities to invest.  What would be the reason to not buy?  If Sigma Labs has not progressed, then I would think to hold or sell.  They have a product and PrintRite3D systems are out in the field, 2 of which were sold for $975,000.  Now that there will be a business model created to establish grounds for commercialization are signs of significant growth.  Sigma Labs has received funding from sales, $3.5M from Rockville Asset Mgmt, and support from GE Aviation and America Makes for distribution.  What aspect of Sigma Labs is not desirable to invest?  Sure, they are not yet commercialized.  However, there are steps proceeding in that direction.  I tend to look at available shares different because I think the current PPS will not dictate what Sigma Labs does, which is offering the only solution for metal 3D fabrication.
