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

NETZSCH 3D Printing Print Temperature

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.

Directed Energy Deposition: Material Science in Additive Manufacturing

NETZSCH_Week 8_Additive Manufacturing

While Powder Bed Fusion and Binder Jetting evolved to also using metals, Directed Energy Deposition was specifically developed for this class of materials. We introduce the process principle and variations, benefits and applications of the Additive Manufacturing technology.

Binder Jetting: Material Science in Additive Manufacturing

NETZSCH_Week 6_Additive Manufacturing

The Additive Manufacturing technology Binder Jetting is very similar to Powder Bed Fusion. Although there are many similarities of the two processes, the material properties that can be achieved are very different. Learn about the process principle and applications of Binder Jetting!

Material Jetting: Material Science in Additive Manufacturing

NETZSCH_Week 5_Additive Manufacturing

This week, we move back from thermoplastics to UV-curing resins, which are deposited in a different way. Together with binder jetting, material jetting is the only Additive Manufacturing process that can print in color. We introduce the process principle and look at benefits and applications of Material Jetting.

Bestimmung des Prozessfensters von SLS-Pulvern mittels DSC

Beim SLS-Verfahren wird das Bauteil schichtweise in einem Pulverbett mit einem Laserstrahl aufgebaut, indem der Strahl über die Oberfläche der Bauteilgeometrie geführt wird, um das Pulver lokal aufzuschmelzen. Um ein Polymerpulver auf seine Eignung für SLS zu charakterisieren und das Prozessfenster zu bestimmen, wird die Dynamische Differenzkalorimetrie (DSC) eingesetzt. Erfahren Sie, wie Sie die Messungen durchführen und welche Schlüsse Sie daraus ziehen können.
