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 Temperatures and EnthalpiesThe enthalpy of fusion of a substance, also known as latent heat, is a measure of the energy input, typically heat, which is necessary to convert a substance from solid to liquid state. The melting point of a substance is the temperature at which it changes state from solid (crystalline) to liquid (isotropic melt).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.
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.
