We remember SGLB certifying 3D-printed rocket components with Aerojet RocketDyne.

“Working alongside Aerojet Rocketdyne on this Air Force program, as well as with America Makes, allows Sigma Labs to once again showcase the benefits of our unique technology,” said Mark Cola, President and CEO of Sigma Labs. “This is a great opportunity for Sigma Labs to gain additional exposure within the aerospace and defense industry, particularly as part of an initiative designed to define standards and qualification requirements for 3D-printed rocket components. We look forward to the rollout of these programs in 2016 and appreciate the trust that both Aerojet Rocketdyne and the U.S. Air Force have placed in Sigma Labs.”
Sigma Inside is coming 2019 to that new Huntsville facility. IMHO.

We know that AR-1 is using 3D printed components.

Aerojet Rocketdyne has reported two significant milestones have been reached in the development of the 3D printed AR1 rocket engine. Following successful hot fire tests, the engine also completed its Critical Design Review (CDR).

As a result, the AR1 engine is on track for certification in 2019 in its bid to replace the Russian made RD-180 rocket engine. The RD-180 is currently used to launch most U.S payloads into space. However, Aerojet has significant competition in the form of aerospace manufacturer Blue Origin and its BE-4 engine.
