Metallurgical Principles for Powder Bed Fusion Processes - Webinar OnDemand

Price: $49
About the Webinar

3D printing of metals has advanced rapidly in the past decade and is used across a wide range of industries. Although laser powder bed fusion (LPBF) has matured the fastest for metals, other technologies such as binder jet and (robotic) wire feed are making substantial progress. Many aspects of technology are well understood in the sense that machines make parts and temperature histories with residual stress can be simulated. Nevertheless, key questions remain open as to how to qualify printers and certify parts, how to control defect structures, which includes surface condition and how to implement more sophisticated control systems.

The following topics will be highlighted in the webinar:

  • Physics of the laser powder bed fusion process (PBF-LB)
  • Use of advanced methods such as ultra-high-speed imaging with dynamic x-ray radiography (DXR), and Synchrotron-based 3D X-ray computed microtomography (µXCT) for process characterization
  • Links between porosity and process conditions in defining a process window
  • Microstructure evolution in the PBF-LB process
  • Machine learning concepts for microstructure classification, and defect detection and classification in the spreading of powder

This OnDemand webinar will take approximately 1 hour and 15 minutes to complete.
