Multi-scale Evaluation of Micro-Porosity, Cracks and Inclusion in AM Parts

Additive manufacturing utilizes layer by layer solidification to create a final part. During this process, many undesirable features such as porosity, cracks, and inclusions of foreign materials can occur through either the raw material or through the sub-optimal process parameters. Detailed characterization of such features is needed in quality control, optimizing process variables and controlling feedstock quality. However, this can often prove challenging for examples pore sizes typically are highly heterogeneous and range from a few mm to µm in a single part. In this presentation, we show how to overcome some of these challenges using ZEISS' multi-scale multi-modal workflow to solve challenges in additively manufactured parts.

Highlights of the webinar:

• Multi-length scale porosity and defect detection
• Non-destructive imaging of small features through a large part using RaaD
• Multi-modal imaging using X-ray CT, microCT and SEM
