From the article: "According to Morris, there aren't enough machines or technicians in the world today to come anywhere close to providing the 100,000 injectors GE wants finished in the next six years. And even if there were, there is still no system to ensure consistency or quality in the raw materials they require, and the technology to scan and inspect internal structures and integrity is primitive at best."
This was over a year ago. I hope Mark Cola and developments in PrintRite3D® have made Greg Morris to think otherwise. Well at least Sigma remains the best choice to our knowledge.
