Characteristics of Powder Metal for 3D Printing

Post by:
  • 3:23PM Apr 21, 2017

In Powder Metals (PM) applications such as 3D printing, the flow and packing behavior of PM is influenced by particle size and shape distributions. These properties can be measured in a statistically meaningful way using computer controlled scanning electron microscopy (CCSEM). In livetime, the SEM program detects a particle, defines its perimeter, calculates its size and […]
