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.
Germany’s long-term goal is to become largely greenhouse gas neutral by 2050. In doing so, the German government is aligning itself with the Paris Agreement’s goal of achieving greenhouse gas neutrality worldwide in the second half of this century. Plastics recycling and materials research play a key role in this.
It’s time to change tires. But is it really necessary to replace summer tires with winter tires every six months? Isn’t it better to do without the two and use all-season tires instead? We will answer that question for you.
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).
AutoEvaluation is an intelligent software algorithm and part of the NETZSCH Proteus® software, which automatically and autonomously evaluates thermo-analytical measurement curves. It has already been introduced and successfully applied for Differential Scanning Calorimetry and Thermogravimetric Analysis and is also available for dL signals as generated by dilatometers (DIL) and thermomechanical analyzers (TMA). As an improvement, the mean CTE (Coefficient of Thermal Expansion) values are evaluated additionally before and after the glass transition.
Thermal Analysis and Rheology comprise essential analytical methods supporting the development of pharmaceuticals and ensuring their quality. Watch our new video and learn how NETZSCH Analyzing & Testing contributes to the development and quality control of pharmaceuticals!
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.
