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!

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.

What TMA Measurements Can Tell About Filler Orientation in Injection Molding

Fillers have long played an important role in the polymer manufacturing industry. An important property to measure how the filled material changes in length when being heated or cooled is the coefficient of thermal expansion. Knowledge about this material behavior is required to be able to determine important design values. Learn how the flow field and sample preparation influences the property and see how measurements with the TMA 402 F3 Hyperion® Polymer Edition are carried out.

Quality Control of Electronic Assemblies Using Thermomechanical Analysis

TMA Polymer Edition Electronic Assemblies1

A major source of failure of electronic assemblies is thermal expansion and the problems it causes. To make sure that the circuit base boards conform to a certain quality, IPC standards were put into place that require measurement of the thermal expansion, glass transition and softening point. Learn how you can comply to the standard with the new TMA 402 F3 Hyperion® Polymer Edition.
