Köstlichkeiten perfektioniert… Optimierung der Rheologie von Schokolade

Schokolade ist eines der beliebtesten Genussprodukte der Welt. Die Textur bzw. das Mundgefühl von Schokolade ist entscheidend für die Wahrnehmung der Produktqualität. Es ist möglich, die Aspekte des charakteristischen Geschmacks von Schokoladen fein zu steuern. Das Mundgefühl kann durch die Bestimmung des Fließverhaltens - durch Rheologie - charakterisiert werden. Erfahren Sie in unserem Artikel, wie das geht!

Material Science in Additive Manufacturing

Additive Manufacturing (AM) or 3D printing has matured over the last decades and has become a constant in our product design and development cycles and is debuting in more and more new products. At NETZSCH Analyzing & Testing, we see more and more customers in the field of Additive Manufacturing using our equipment to select materials and optimize their processes. Learn more about Additive Manufacturing in our articles and videos!

Investigating UV Exposure and Thermal Cure in Vat Photopolymerization

During the Vat Photopolymerization process, the component is built-up in layers in a liquid resin vat using a UV laser beam to selectively cure the resin. Learn how the degree of thermal cross-linking of a two-component resin is determined by the preceding cross-linking reaction during photo-polymerization.

How to Detect Cure State of Pre-Cured Composite Samples

Popular materials for lightweight applications are glass and carbon fiber-reinforced plastics. The properties of the composite material are determined by the manufacturing process conditions. Therefore, it is crucial to know the curing state reached during manufacturing as well as the correlation between the glass transition temperature and degree of cure.

Material Science in Additive Manufacturing: Our Advanced Series!

In 2020, we started our “Material Science in Additive Manufacturing” video series as we faced an increasing interest from the industry to perfect their 3D printing processes and outcomes. First, we focused on understanding the 7 different Additive Manufacturing (AM) technologies. In the advanced section, we will dive deeper and look at the underlying material science as well as the methods suitable to analyze the materials and to optimize processes.

Measuring Specific Heat Capacity to Simulate SLS Processes

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!

Why Does My 3D Print Warp and How to Stop It

Dr. Natalie Rudolph explains the basics of shrinkage and warpage of plastic parts and introduces the right analytical instrument to determine the shrinkage potential of different materials. She gives important tips for home users to avoid warpage and curling during the 3D printing process.

Der Wärmeausdehnungskoeffizient: Eine entscheidende Materialeigenschaft

Bei der Konstruktion von Bauteilen und Komponenten aus Faserverbundwerkstoffen muss der Wärmeausdehnungskoeffizient berücksichtigt werden, denn er bestimmt, wie stark sich ein Material bei Erwärmung oder Abkühlung in seinen Dimensionen verändert. Thermomechanische Analyse (TMA) ist die perfekte Methode für die Vorhersage der Produktleistung und des Verarbeitungsverhaltens. Lesen Sie unseren Beitrag in der Zeitschrift Kunststoffe!

How do I Find the Perfect Print Temperature for my Filament?

Dr. Natalie Rudolph explains which aspects have to be taken into account to find the best print temperature for your 3D printer. Most importantly, she introduces the Modified Melt Flow Test, which allows home users to easily determine the perfect print temperature for any given filament. All that is needed are a stop watch, a kitchen scale and a sharp object, e.g. a spatula.

New: Additive Manufacturing Materials in Identify

The Identify software is one of a kind in the field of Thermal Analysis. Via database comparisons, it only takes a second for Identify to identify and classify your samples. We have added Additive Manufacturing materials to our database! Read more in the article!
