Z,

I forgot about that GE intern article that I found at the end of this summer. I referenced it in my post. http://investorshub.advfn.com/boards/read_msg.aspx?message_id=116353179

Here's the link to that article from GE's site.

This is the technology that I believe could be our thermal solution and here is the dot connecting rationale. Windbag sent this to C. Witty and the response was no comment as I recall. I wish jj was around to get his take on it.

Another reason why I believe that we are involved with the infared pulse thermography that the GE intern spoke of is because we were part of the team that won the NIST award.

"In the area of process metrology for validating process models, this project will collaborate with the AM Qualification project in developing traceable infrared thermography and spectroscopy methods for measuring the temperature distribution of the melt pool in powder bed fusion processes. Validated physics-based process models will be used to develop reduced-order analytical models for use in development of real-time control algorithms."

Our patent does mention

Quote:
"A real-time thermal measurement 11 can be made using any variety of contact or non-contact measurement methods, such as infrared cameras, pyrometers, or thermocouples. The measurement method can be fast enough in terms of its response time to be consistent with the desired update loop of the controller 14."


Quote:
"A method for control of a fusion welding process by maintaining a constant weld pool volume comprises generating a weld pool using a welding machine tool having a plurality of process variable settings, making a thermal measurement of the weld pool using a thermal sensor, solving a thermal inverse model to predict the thermal response of the weld pool to the plurality of process variable settings, comparing the predicted thermal response of the weld pool to the thermal measurement of the weld pool, and changing at least one process variable setting of the welding machine tool in response to the comparison of the predicted thermal response and the thermal measurement of the weld pool."

“In-Process Quality Assurance (IPQA) for Laser Powder Bed Production of Aerospace Components”
- General Electric Aviation
Led by General Electric Aviation, in partnership with Aerojet Rocketdyne; B6 Sigma, Inc.; Burke E. Porter Machinery Company; Honeywell Aerospace; Montana Tech of The University of Montana; and TechSolve, Inc., this project will address the need for the development of a commercially available, platform-independent Quality Assurance technology for high-volume AM production of aerospace components, which is currently lacking within the industry. The proposed effort will be achieved through the maturation of an IPQA technology solution that leverages a development approach, incorporating multiple AM machines and multiple super alloys.

GE, Aerojet and Honeywell along with SGLB working on maturation of an IPQA technology. We have the IPQA technology that they are working on maturing and I believe that the infared pulse thermography is our patent that they are developing. We own the patent that's why they are contracting with us to purchase units of PrinteRite3D which will have Inspect and soon Deform and I'm betting that our Thermal is the infared pulse thermography that is being developed. Good Luck Longs!
