Additive Manufacturing at GE – Revolutionizing the
Way We Think
David H. Abbott, GE Aviation
Additive manufacturing (AM) has recently exploded
onto the scene, challenging preconceived notions about
designing, producing, and even using complex 3D geome-
try. Compared to the previous two or three industrial rev-
olutions, change is happening at an ever accelerating rate
due to recent technological advances. GE is also experi-
encing sweeping changes. AM is not only changing how
engineers design and build, but also how they think. It is
evolving into more than just another design or manufac-
turing tool. It is becoming a way of life.
EDUCATION SHORT COURSES
Make the most of your AeroMat experience and take
an education short course. The 2014 courses are conve-
niently scheduled post conference, June 19, at the Gaylord
Palms Resort and Convention Center.
Titanium and Its Alloys
Instructor: Rodney Boyer, FASM
Date: Thursday, June 19
Time: 8:30 a.m. – 4:30 p.m.
Titanium and its alloys are a versatile family of metals
with applications in many industries. They have high
strength-to-weight ratios, excellent corrosion resistance, high
and low temperature capabilities, and compatibility with
graphite fibers, which are gaining importance with the in-
creased use of composites in aircraft structure. This unique
combination of physical, mechanical, and chemical proper-
ties makes them attractive for aerospace, marine, industrial,
biomedical, and other applications. This course provides an
overview of titanium alloy processing, from refining ore to
machining hardware, and discusses how the unique proper-
ties of titanium drive applications in various industries.
Additive Manufacturing
Instructor: Frank Medina
Date: Thursday, June 19
Time: 8:30 a.m. – 4:30 p.m.
This course covers various aspects of additive, subtrac-
tive, and joining processes to form 3D parts with applica-
tions ranging from prototyping to production. Additive
manufacturing (AM) technologies fabricate 3D parts using
layer-based manufacturing processes directly from com-
puter-aided-design (CAD) models. Direct digital manufac-
turing (DDM) or rapid manufacturing (RM) involves the
use of AM technologies in direct manufacturing of end-
use parts. Learn about a variety of AM and other manu-
facturing technologies, their advantages and disadvantages
for producing both prototypes and functional production
quality parts, and some of the important research chal-
lenges associated with using these technologies.
Modeling of Heat Treatment Processes for Steel Parts
Instructors: B. Lynn Ferguson, Ph.D.,
Zhichao (Charlie) Li, Ph.D., Andrew Freborg, PE, MS
Date: Thursday, June 19
Time: 8:30 a.m. - 4:30 p.m.
This course is designed to introduce analytical mod-
eling to the heat treating industry. The focus is on the
usefulness of modeling results in terms of understanding
and improving heat treatment processes for steel parts,
including carburization methods and hardening using a
variety of quenching media. The material data and
process variables requirements for accurate analytical
models will also be presented. Case studies that demon-
strate the dependence of distortion and residual stress
state on the heat treat process parameters and steel alloy
hardenability will be presented.
