Powder
Processing & Additive Manufacturing Module
Outcomes
1. Be able to describe the series
of steps required for powder processing and additive manufacturing
2. Be able to connect the
scientific principles, engineering challenges, current engineering practice and
non-technical issues associated with each individual step and overall process

Chapters
15 and 16 of the text focus on Powder Processing (Metals and Ceramics
respectively). Consider all the associated steps: 1) atomization, 2) blending, 3)
compaction, and 4) sintering. Figure 15.12 is one of the best illustrations of
sintering I have seen. Compare the powder processing of metals and ceramics.
For example compare a blend to a slurry. Chapter 32 of the text is a good
overview of additive manufacturing, which has become known as 3-D printing. The
following YouTube videos give you a great overview and set of applications
ð
As
you watch the text video giving an overview
of powder metallurgy pay careful attention to the controlled porosity and
compare it to the shrinkage associated with casting. The YouTube Video on melt atomization
describes how starting with molten metal one can form metal powders.
