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.
- 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

Measuring Specific Heat Capacity to Simulate SLS Processes
Significant efforts have been made to model and simulate the Selective Laser Sintering process as information about the temperature field in lower layers is difficult to measure. Learn how the specific heat capacity can help!
In our next episode, we will talk about estimating residual stresses in PBF parts using DMA.
