Material Science in Additive Manufacturing: Specific Heat Capacity of PA12 Powder

In our previous episode, Dr. Natalie Rudolph informed about the isothermal measurements and their importance for process simulation. Today, we talk about measuring the specific heat capacity of Powder Bed Fusion Powder and what it is needed for.

In our previous episode, Dr. Natalie Rudolph informed about isothermal measurements and their importance for process simulation. Today, we talk about measuring the specific heat capacity of PA12 powder for the Additive Manufacturing technology Polymer Powder Bed Fusion (PBF) and what it is needed for.

This week’s topic: Specific Heat Capacity of PBF Powder

We use Differential Scanning Calorimetry (DSC) heat flux method to measure the difference in heat to detect exothermal and endothermal effects.

Learn about:

  • The importance of heat capacity for any kind of thermal simulation
  • The difference of the method of measuring the heat capacity compared to a conventional DSC measurement
  • An application example with PA12
  • Using the specific heat capacity to calculate the thermal conductivity
