Material Science in Additive Manufacturing: Warpage Prediction of PBF Parts Using CTE

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.

One Click AutoEvaluation for Dilatometer Signals (dL) Improved

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.

Estimating Warpage of Selective Laser Sintering Parts Using Thermomechanical Analysis

Warpage SLS TMA NETZSCH

The plastics used in Selective Laser Sintering (SLS) have a higher thermal expansion when compared with other materials. Therefore, it is important to know how the dimensions of an SLS part change at different temperatures during the build and during use. The higher the thermal expansion coefficient, the more prone are the parts to warpage or curling and the build-up of residual stresses. Learn more!

Smart Thermal Analysis: Measurements Wanted?

Imagine the typical situation in everyday laboratory work: A new sample has to be analyzed, but what are the suitable measurement conditions such as temperature program, sample mass or the right crucible? And what measurement results can be expected? Perhaps such kind of sample was already measured by you in the past ‒ or maybe by NETZSCH. Wouldn’t it help a lot to simply search in a database for thermal analysis? Identify, which is a part of the Proteus® analysis software, is the solution!

Unique Tool for the Prediction of Product Performance and Processing Behavior under Thermal Expansion Control

The New TMA 402 F3 Hyperion® Polymer Edition Modern products made of polymers are all around us. Polymers are used for everyday products but also for challenging applications. The tricky bit is to assure compatibility when different polymers are joined together. For blends or compounds, such as composite materials, the prediction of material behavior in … Read more

Why Knowledge About Anisotropy is Crucial when Designing High-Performance Composite Parts

Fiber-reinforced composite materials, which combine the properties of fibers and a polymer matrix, have been around for decades. There are different ways to incorporate the fiber into the thermoplastic matrix ‒ randomly oriented fibers, unidirectional continuous fibers or multi-directional fabric. The orientation of the added fibers plays an important part when it comes to part properties. Learn why anisotropic behavior of the composite is favorable and how to measure it with the TMA 402 F3 Hyperion® Polymer Edition.
