Metal Based Additive Manufacturing Analysis Webinar

In this webinar we introduce Metal Based Additive Manufacturing Analysis to understand and evaluate many aspects of the metallurgy.

In 2010, the first standard, ASTM F2792-10, additive manufacturing (AM) is defined as:
“The process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing technologies.”

In accordance to the ASTM F42 Committee on Additive Manufacturing, there are four process categories that is metal-based AM:

  • Powder bed fusion (PBF)
    a. Selective laser melting (SLM)
    b. Electron beam melting (EBM)
  • Direct energy deposition (DED)
    a. Laser vs. e-beam
    b. Wire fed vs. powder fed
  • Binder jetting
    a. Infiltration
    b. Consolidation
  • Sheet lamination
    a. Ultrasonic additive manufacturing (UAM)

Focusing solely on metal-based AM, we will discuss how scan strategy can affect the energy applied in the form of beam interactions and heat transfer thereby defect formation, melt pool geometry, solidification and cooling will. We will also touch on how feedstock quality and purity dictates material chemistry and plays a direct role in microstructural evolution which directly affects mechanical integrity. To achieve the desired properties of your AM part/component, it is important to understand and evaluate many aspects of the metallurgy in order to understand the affects of the process. Examples of the most commonly researched and documented alloys such as titanium and nickel will be used as examples.

In this webinar we will cover:

  • Four categories of Metal-based AM
  • Processing effects on metallurgy
  • Processing effects on defects
  • Common AM metal alloys as examples
