Also, Sigma could have a tie to 4026 through Honeywell, one of the team members.

A collaborative team of three, highly technical, and
competitive aerospace OEMs—GE, Honeywell and United
Technologies Research Center (UTRC)—worked together
with software developers 3DSIM, Pan Computing, and
CDI Corporation to:
• Develop and build canonical geometries for use in
validating the distortion tools.

From the last Sigma 10-K in March of 2016:

Lastly, we are currently a subcontractor to Honeywell Aerospace who was awarded a program in 2015 by America Makes which is designed to address "Design for Additive Manufacturing" ("DFAM") issues. In support of this program, we will use our EOS M290 AM system to build canonical shapes and mechanical test specimens for evaluation by Honeywell Aerospace.
