material coupling, resulting in lower power
requirements and less material ejections
during the process, resulting in a more
economical process and less defect-prone
parts.
With newer approaches to manufacture
metal powder like the MPW process, the
benefit could be that more alloys are
available and faster produced with almost
no CO2 emissions. Today, there are 16
approved AMS metal powder
specifications but over 2,000 approved
AMS metal bar specifications. There is
room for optimism.
The early hype of metal additive
manufacturing in the early 2010s resulted in
enthusiasm. What came next was the
responsibility to deliver economically
sustainable material systems, flexible and
environmentally friendly raw material
production technologies, along with
competent and economical approaches to

adopt these materials for metal AM
production. Teams such as the MPW/
MSAM/TBGA are one of the keys toward
this vision. n
