In our last episodes, we focused mainly on thermal material behavior measured with Differential Scanning Calorimetry (DSC). Today, Dr. Nathalie Rudolph will talk about how residual stresses can be estimated using Dynamic Mechanical Analysis (DMA).
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.
Today’s focus is on the crystallization behavior in Polymer Powder Bed Fusion using Differential Scanning Calorimetry (DSC). Find out more about the time dependence of crystallization with the example of a semi-crystalline thermoplastic and learn about isothermal crystallization of Nylon PA12 powder.
Powder Bed Fusion (PBF) is one of the most used Additive Manufacturing technologies to produce structural plastic parts. Learn today how to determine the process window of Polymer PBF using thermal analysis.
Find out more about process parameters and the properties of the starting material including how these affect the properties of the final parts and components.
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 specific heat capacity can help!
Additive Manufacturing (AM) encompasses a variety of technologies suitable for producing components from liquid, solid or powder feedstocks. Selective Laser Melting (SLM), a powder-bed fusion process, has become a commonly used AM process for rapid prototyping and component manufacturing using metals, alloys and, to a lesser extent, ceramics. Learn more about SLM, suitable materials and how to optimize input parameters for improved product quality using Thermal Analysis.
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.
This week, we are moving from thermosets to thermoplastics and specifically the Powder Bed Fusion process. It is an Additive Manufacturing process in which thermal energy selectively fuses regions of a powder bed (ASTM F42 Committee).
