That must mean they didn't sell it either, so that must mean that there were ZERO revenues from the past many months from their premier product.
So what product is this one?
"...Solar Turbines will implement Sigma Labs’ In-Process Quality Assurance™ (IPQA®) technology for the production of gas turbine components using metal additive manufacturing (“AM”)..."
They announced the unveiling of a product (2.0) months ago and now we find out it just now actually came out, having been neither for sale not available all this time...Therefore the first announcement was misleading. Probably just some garbage to stop the constantly bleeding share price.
