Jackle,
Interesting about that polymer 3D from NASA site.
A Fully Nonmetallic Gas Turbine Engine Enabled by Additive Manufacturing
Part II: Additive Manufacturing and Characterization of Polymer Composites

It so happens that Honeywell did some work with Stratasys on this

"All the FDM printing was performed at Rapid Prototype Plus Manufacturing (rp+m), using Stratasys’ open source Fortus 400 or 900 mc FDM machines. The experimental XH6050 resin and carbon-fiber-filled Ultem 1000 filaments were supplied by Stratasys under the Ohio Third Frontier Program—Advanced
Materials for Additive Manufacturing Maturation. The Ultem resins and composites were printed between 375 to 420 °C (707 to 788 °F). The specific engine components were selected by Honeywell Aerospace.

It so happens that Stratasys, Honeywell and Concept Laser teamed up at Arizona State

As the largest additive manufacturing center in the American Southwest, the Additive Manufacturing Center is dedicated to keeping students, faculty and industry partners on the forefront of the rapidly growing additive manufacturing sector.
With the use of cutting edge plastic, polymer and metal 3D printing equipment, along with advanced processing and analysis capabilities, the Additive Manufacturing Center is the premier hub to develop the next generation of manufacturing engineers in conjunction with industry partners.
Partners
Formed as a partnership between Arizona State University, Honeywell Aerospace, Concept Laser, Inc., PADT Inc., Intel and Stratasys Ltd., the center is home to $2 million in state-of-the-art additive manufacturing equipment.

It also happens that Stratasys recently announced

The aerospace certification solution consists of a new ULTEM™ 9085 resin and a, “new edition of the Fortus 900mc Production 3D Printer with specialized hardware and software designed to deliver highly repeatable mechanical properties.

It also happens that Siemens and Stratasys announced that partnership

to integrate Siemens’ Digital Factory solutions with Stratasys’ additive manufacturing solutions.

This leads to what you mentioned about SGLB's recent announcement which

broaden the market reach of the Company's PrintRite3D® technology to the Smart Factory and the larger Digital Enterprise, including polymer-based 3D printing.https://globenewswire.com/news-release/2017/07/06/1039663/0/en/Sigma-Labs-Inc-Announces-Alliance-with-OXYS-Corporation-of-Cambridge-MA-to-Bring-Industrie-4-0-Solutions-to-Additive-Manufacturing-and-the-Broader-Digital-Enterprise.html

I bet PrintRite3D is part of that aerospace certification solution. I'm looking forward to the next few years here
