Additive manufacturing (AM) is currently revolutionizing the manufacturing world, as it can be used to produce more complex and lighter parts while reducing waste when compared to traditional approaches. In powder bed fusion processes—such as SLS, SLM and EBM—materials are selectively fused layer-by-layer to form a three-dimensional part. However, the properties of that part are highly dependent on the properties of the powder feedstock used, including particle size and shape.

In this webinar Dr. Paul Carpinone will discuss the impact of particle size and shape on powder bed formation, powder spreading and melt characteristics, and how they impact the AM process. He will also discuss the various analytical techniques for measuring these characteristics with an emphasis on laser diffraction, dynamic image analysis and static image analysis.
