Powder Bed Fusion (PBF), auch als Selektives Lasersintern (SLS) bezeichnet, ist eine Technologie zum schichtweisen Aufbau von 3D-Objekten, bei der ein Laserstrahl selektiv über einen vordefinierten Bereich der Pulverschicht fährt. Eines der dabei am häufigsten verwendeten Materialien ist PA12.
Powder Bed Fusion (PBF), also called Selective Laser Sintering (SLS), is the layer-by-layer construction technology of 3D objects, where a laser beam selectively traces over a predefined area on the powder layer. One of the most widely used materials is PA12.
Today, Dr. Natalie Rudolph will talk about the refreshing strategy for Powder Bed Fusion powders using Differential Scanning Calorimetry. In this episode, not the part properties, but the properties of the powder will be investigated.
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.
The modification of Selective Laser Sintering (SLS) powders with fillers is a good way to modify the properties of the produced parts without the necessity for new powder materials. Learn how to assess the effect of copper fillers on the processing behavior.
