Today, Dr. Natalie Rudolph will explain how the thermal diffusivity of a powder bed fusion part can be measured using Laser Flash Analysis (LFA) and how it can be computed in thermal conductivity.
In general, the addition of fillers leads to an increase in mechanical performance. While a critical length of the fillers is needed to have an effect on the strength of components, the stiffness is already increased with fillers with small aspect ratios. To understand how the stiffness or modulus change as a function of the filler geometry and filler content, Dynamic Mechanical Analysis (DMA) can be used. Learn more in our article!
Residual stress can lead to warpage of a 3D-printed part. Both Dynamic Mechanical and Thermomechanical Analysis are capable to estimate warpage. In this video, Dr. Natalie Rudolph explains, how the coefficient of thermal expansion (CTE), measured with Thermomechanical Analysis, can be used to predict and calculate warpage.
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.
A way to reduce shrinkage and increase dimensional stability of polymers is the addition of inorganic fillers, for instance glass beads. Learn how to determinethermal expansion of 3D printed samples – both unfilled and filled with hollows glass beads.
Metal-based Additive Manufacturing (AM) encompasses a wide range of technologies such as powder bed fusion (PBF) and metal binder jetting. Learn about the molecular structure of metals and why phase diagrams are important for AM processes.
