Taking Flight - Troubleshooting Additive Manufacturing Powders in Aerospace

Webinar Recording

As materials and process experts, with extensive cross-industry experience, we provide materials and process development for key technologies within the aerospace and defense industries - including Additive Manufacturing (AM).

At Lucideon, our team of metallurgists are highly experienced and knowledgeable across all types of commercially available AM technologies, from Direct Metal Laser Sintering (DMLS), Electron Beam Melting (EBM) and Electron Beam Additive Manufacturing (EBAM), to Directed Energy Deposition (DED) and Binder Jet. We specialize in providing engineering services which are supported by customized testing and analysis from our state-of-the-art laboratories.

During this webinar, our principal consultant for metallurgy, Julius Bonini, discusses metal AM and the associated powder issues.

Webinar Contents

Review of the three metal additive manufacturing methods

  • The basic methods
  • General powder issues associated with each method
  • Specific flow and recycling issues.

Review of how metal powders are made

  • Atomization methods, differences in quality and costs
  • Powder quality and consistency
  • Powder morphology
  • The importance of size.

Testing and evaluation of powder

  • Powder sampling and appropriate methods
  • Flow testing and its inadequacy
  • Standard chemistry methods
  • The meaning of density testing
  • Particle Size Distribution (PSD)
  • Consistency issues
  • Best real methods of evaluation - SEM imaging and metallographic cross-sections of powder.

Powder issues and problems

  • Flow - to fill or not to fill
  • Recycling concerns - what do you do with all that unused powder?
  • Consistency - run to run, batch to batch, lot to lot, machine to machine - consistency is hard to find.
