Variations of Powder Bed Fusion: Material Science in Additive Manufacturing

Variations of Powder Bed Fusion: Material Science in Additive Manufacturing

Powder Bed Fusion (PBF) is one of the oldest Additive Manufacturing technologies invented in the 80s. However, its suitability for end-use parts and its constant innovations are driving this technology further ahead. This week we look at two important variations of Powder Bed Fusion.

Last week, we concentrated on the Additive Manufacturing technology Powder Bed Fusion (PBF). Focus was on Polymer Powder Bed Fusion using thermoplastics for the built up of components.

Evolution of Powder Bed Fusion

Powder Bed Fusion (PBF) is one of the oldest Additive Manufacturing technologies invented in the 80s. However, its suitability for end-use parts and its constant innovations are driving this technology further ahead. First, we look at Metal Powder Bed Fusion, often called Selective Laser Melting (SLM). Second, we emphasize Multi Jet Fusion (MJF), which is an innovative variation to PBF also using thermoplastics.

Overview of Metal Powder Bed Fusion (SLM, DSLM)

Powder Bed Fusion for polymers and for metals have many similarities and share the same definition. In this video, I highlight the distinguishing features in the process principle and look at advantages and disadvantages of this Additive Manufacturing technology.

Overview of Multi Jet Fusion (MJF) ‒ a PBF Variation

One of the Additive Manufacturing processes that was developed by challenging the traditional laser- based process of powder Bed Fusion (PBF) is Multi Jet Fusion (MJF). I explain the difference to PBF and highlight important advantages and applications.
