22 Where AM Meets AI
A Colorado alliance has found the link between AM
and AI. Using machine learning to map the formula for
successful metal 3D printing, researchers aim to know
the right parameters for any new part with few or no test
builds.

28 Machine Learning Applied to Metal Powder
A computer vision system that has learned to classify
metal powders could speed material qualification and
advance machine learning in additive manufacturing.

32 What GE's Machine Learning Ecosystem
Will Mean for AM
At GE's Global Research Center in upstate New York,
engineers join forces to build a digital library of additive
research.
By Brent Donaldson
12 Taking Shape
• The Post-Production Challenge for Additive
Manufacturing
• AM Design May (Finally) Launch the Aerospike
Engine

ABOUT THE COVER: These various test specimens
were made for evaluation by the ADAPT Center at the
Colorado School of Mines. Test parts such as these are
made with many different combinations of variables in
the same build, including (as can be seen here) many
different angles relative to the recoater blade. Gathering
data on a large quantity of process inputs and measured
outputs will allow machine learning to be used to deduce
the "rules" for successful additive manufacturing.
