    How will failure analysis of additive manufactured materials differ from traditional failure analysis?

    Thoughts? @Daniel Dennies, @Elvin Beach or @Larry Hanke

    History of the part is always important but often hard to obtain.  AM parts will raise this up a notch as lot traceability will likely include small batches and potentially even harder to trace back to any raw material, tooling or operator influence.  Porosity of the finished material will also become more important to characterize.

    Hi John,
    I think that the failure analysis methodology of AM parts will not differ from traditional. The fracture surfaces may show sometimes new phases since we know now that AM is capable to produce phases that are usually not found in traditional materials, but this could be characterized by the methods used for failure analysis i.e. SEM/EDAX, and by microstructure observations on cut-ups from failed parts. If you are familiar with welding microstructure and already made failure investigations on welded components, you'll be able to see that it'll help for the investigation on AM pieces.
    Hope this help.
