Sigma Labs’ In-Process Technology to Overcome Barriers in Metal 3D Printing

The National Institute of Technology (NIST) recognizes the need for in-process sensing and control for the broader acceptance of metal 3D printing. Variation in part quality due to defects in the layer-by-layer additive process restricts the application of metal 3D printing for safety-critical applications. The aerospace and automotive industries would like to add 3D printing technology to their manufacturing scope but part inconsistencies impede its full adoption. There is a lack of quality control and the NIST recognizes a critical need for real-time measurement tools for the understanding of the printing process. By knowing what takes place during the printing process can the control methods be developed to absolve the dilemma of quality assurance in metal 3D printing?
