Powder Bed Fusion (PBF) is one of the oldest Additive Manufacturing technologies invented in the 80s. However, its suitability for end-use parts and its constant innovations are driving this technology further ahead. This week we look at two important variations of Powder Bed Fusion.
Powder Bed Fusion (PBF), often called Selective Laser Sintering (SLS), the component is built up in layers in a powder bed using a laser beam that passes over the cross-section of the layer to locally melt the powder. In order to characterize a polymer powder for its suitability for SLS and to determine the possible process window, Differential Scanning Calorimetry (DSC) is used. Learn how to set up and interpret the measurements!
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.
Powder Bed Fusion (PBF), often called Selective Laser Sintering (SLS), is one of the most used Additive Manufacturing technologies to produce structural plastic parts. In this article, we explain the process principle and materials used in the SLS process.
This week, we are moving from thermosets to thermoplastics and specifically the Powder Bed Fusion process. It is an Additive Manufacturing process in which thermal energy selectively fuses regions of a powder bed (ASTM F42 Committee).
This week, the spotlight is on the Additive Manufacturing technology Vat Photopolymerization (VP, SLA, DLP). I explain the general process principle and its variations. Furthermore, I look at the material class that is commonly used and discuss benefits and applications of the process.
Additive Manufacturing (AM) oder 3D-Druck ist zu einer Konstanten in unseren Produktdesign- und Entwicklungszyklen geworden und hält Einzug in immer mehr neue Produkte. Bei NETZSCH Analysieren & Prüfen sehen wir immer mehr Kunden aus dem Bereich der additiven Fertigung, die unsere Instrumente zur Materialauswahl und Prozessoptimierung einsetzen. Aus diesem Grund haben wir diese Videoserie vorbereitet und freuen uns, endlich mit unserer Videoserie “Materialwissenschaft in der Additiven Fertigung” zu starten.
Welcome to week 1 of Material Science in Additive Manufacturing! This initial week of our video series is dedicated to generating a common understanding of Additive Manufacturing (AM), the different categories and tradenames along with the typical process flow. Enjoy!
Additive Manufacturing (AM) or 3D printing 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. That is why we have been busy preparing this special video series and are excited to finally launch “Material Science in Additive Manufacturing”.
Additive Manufacturing (AM) has been around for several years. The main application for a long time was prototyping in the early stages of product development. Recently, new technologies like Digital Light Synthesis (DLS) are shaking up the AM sector. Using DLS and a two-stage dual-curing process, 3D printing is now being considered for mass production of parts since it has become considerably faster and the final product shows improved mechanical characteristics.
