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.
A way to reduce shrinkage and increase dimensional stability of polymers is the addition of inorganic fillers, for instance glass beads. Learn how to determinethermal expansion of 3D printed samples – both unfilled and filled with hollows glass beads.
The build orientation of samples has an effect on the mechanical properties of Selective Laser Sintering (SLS) parts. Therefore, thermophysical properties need to be assessed in different directions. Learn how to prepare filled samples for laser flash analysis!
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.
Due to the still limited number of available materials for the Selective Laser Sintering process, there is a constant demand for materials with different properties. The addition of any filler to SLS powder typically has an effect on the processing behavior. Today, we investigate the crystallization behavior of PA12 powder filled with copper spheres and flakes.
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!
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
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!
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!
