In summary, Sigma has commercial software that can solve the quality and reliability challenges facing
additive manufacturing today. Its software can be used during material and process (M&P) development
to quickly characterize and quantitatively map a process space by generating digital, in-situ process
metric data. Its commercial software in conjunction with its proprietary probabilistic space-filling DOE,
can help to eliminate the traditional “trial and error” approach to process mapping and validation.
Furthermore, Sigma’s in-situ software can shorten the time and reduce the cost associated with today’s
“make and break” approach to process qualification/certification.
Looking forward, it appears that Sigma’s digital, in-situ process data metrics are strong candidates for
closing the loop and moving the industry towards self-correcting processes using a science-based
approach.
In conclusion, Sigma’s proprietary In-Process Quality Metric™ TED™ represents a very good candidate
for identifying melt pool/process disturbances and closed loop control for metal additive manufacturing.
