Sigma Labs, developers of the in-process quality control system PrintRite3D, has been hoping to establish itself as a necessary part of integrating 3D printing into mainstream manufacturing. After signing deals with large OEMs, like Honeywell, the company continues to push its quality control technology further, most recently filing a patent for a “sensor invention” that will improve additive manufacturing quality control.
On March 25, Sigma Labs filed a patent for a “unique sensor invention that will significantly enhance the ability to improve the quality of additive manufacturing processes especially for critical metal parts like those for aerospace, automotive and defense.” As potentially dull as a sensor might be, the aerospace and defense manufacturers have been demanding better quality control and reliability on the part of 3D printer manufacturers.…
