GE Aviation Signs Additive Manufacturing Cooperative Agreement with Sigma Labs
In-Process Inspection Technology Progresses Additive Production Speeds
EVENDALE, OHIO - May 24, 2013 - GE Aviation and Sigma Labs, Inc. signed a Joint
Technology Development Agreement (JTDA) to advance and implement in-process
inspection technologies for additive manufactured jet engine components.
The mutually-developed inspection technology will verify the quality and
geometry of additive components during the additive build process, increasing
additive production speeds up to 25 percent in support of GE Aviation's growing
"Today, post-build inspection procedures account for as much as 25 percent of
the time required to produce an additively manufactured engine component," said
Greg Morris, GE Aviation's business development leader for additive
manufacturing. "By conducting those inspection procedures while the component
is being built, GE Aviation and Sigma labs will expedite production rates for
GE's additive manufactured engine components like the LEAP fuel nozzle."
Mark Cola, President and Chief Executive Officer of Sigma Labs, stated, "We are
pleased to have signed the agreement and to begin the next phase in
demonstrating our PrintRite3D(tm) technology for additive manufacturing of
metal parts. Together, we will be focusing our efforts in working to assure the
build quality and as-built repeatability of additively manufactured aircraft
engine components, thereby ensuring predictable materials properties critical
to successful product commercialization."
By 2020, GE Aviation will produce more than 100,000 additive manufactured
components for the LEAP(tm) and GE9X engines. GE will install 19 additive
manufactured fuel nozzles on every LEAP engine, which has amassed more than
4,500 orders. The LEAP fuel nozzle is up to 25 percent lighter and five-times
more durable than traditionally manufactured fuel nozzles, leading to
significant fuel savings.
Additive manufacturing enables optimized designs for complex components. GE
Aviation uses additive manufacturing methods such as direct metal laser melting
(DMLM) to build 3D-designed production engine components that traditional
manufacturing methods are incapable of producing.
GE's additive manufactured components weigh less than conventional parts
because they replace complex assemblies with single pieces, reducing the need
for brazing and welding. Additive manufacturing also generates less scrap
material during the fabrication process.
The additive manufacturing process involves taking digital designs from
computer aided design (CAD) software, and laying horizontal cross-sections to
manufacture the part. The process creates the layered cross-sections using a
laser beam to melt the raw material.
