Sigma Labs Inc (SASI)

[GetRich1day]

I still believe that the GE connection exists. As they are working with Honeywell on the ICME framework. Most Longs on this board know that I think Sigma Labs inclusion in the ICME framework is the SGLB's biggest achievement to date. I will agree that the pps does suck and most investors have moved on to other pastures. I'll give props to Alanthill for calling this a long time ago. I have disagreed with him over the years but his assessment has been on target based on where the pps is now. I still strongly believe in the future success of SGLB and maybe that's my downfall but I'm pretty pigheaded when I believe in my DD. I'm still here holding my bag of shares. These days I tend to review my DD to verify my position. It's DD like this that continues to keep me right here.

The framework presented in Fig. 2 contains within the dotted line box the set of ICME tools needed to achieve rapid qualification. A micro-model which describes the melting of the powder and solidification of the material to form the part, and a macro-model which describes the residual stresses that build up as a result of the rapid cooling and solidification of the material. Both of these models were developed by ESI to simulate the powder-bed laser additive manufacturing process. QuesTek® developed the models to predict the material microstructure that develops as a result of the heat treatment process along with a model to predict the tensile properties of the resulting microstructure. Sigma Labs and Stratonics developed techniques for in situ monitoring of the process. Sigma Labs uses a pyrometer to monitor the response of the melt pool whereas Stratonics uses a digital imaging technique to capture the response of the melt pool. Furthermore, Sigma Labs has implemented their In-Process-Quality-Assurance (IPQA) technologies to determine if and when the process may be out of control. Honeywell is implementing non-destructive evaluation (NDE) methods to determine if defects that may develop in the part during the manufacturing process can be detected by inspection. SwRI® is developing the probabilistic design and uncertainty quantification tools to be able to define the minimum predicted material property and risk derived from the novel manufacturing process. Lastly, Honeywell is developing the overall rapid qualification framework to bring all these technologies together in order to demonstrate an acceptable means of compliance with extensive use of simulation models.

A probabilistic framework is proposed for rapid qualification of aerospace components. It leverages knowledge generated by ICME models regarding the manufacturing process and material behavior that can be used to identify testing needed for model development and for evidence of compliance.

In-process monitoring is used to validate the models as well as In-Process Quality Assurance™. The sensors and corresponding IPQA® provide the link between specification and numerical process window selection to the actual build and final product. The uncertainty quantification tools provide a probabilistic foundation for decision making enabling the assessment of overall process risk.

Many Longs are paying the price right now for being visionaries with SGLB. I still believe in the DD not just what Mark says but what I can verify from industry. This framework is coming and from all my DD this ICME framework will be adopted across the military and industry. GE needs to rapidly certify parts to meet the LEAP demand and timeframes that are set. The AM standards are being developed per recent America Makes and ANSI final draft guidance last week . America Makes IPQA project is set to end next quarter. Everything is coming together in time to converge sometime next year as GE ramps up to full scale LEAP production. I firmly believe that GE and others will need IPQA to rapidly certify their product. IPQA will be a part of the myriad of technologies pulled together to make this all happen. That is my humble opinion. Good Luck All!
