Additive Manufacturing in Computed Tomography

In this episode, we will discuss how X-ray computed tomography (CT) can non-destructively access these internal structures, voids, cracks, as well as the external shape. Dimensional inspection including actual to nominal comparison, section thickness,  mechanical load distribution of final product, as well as metal powder morphology are characterized for both qualitative visual inspection and quantitative analysis. Analysis examples from various AM feedstock, such as polymer, metal, and ceramic will be discussed. 

Functional Failure Analysis

In this episode, we will define what a functional failure is and review how you can use X-ray CT to characterize various defects that can cause diminished or loss of function.

Structural Failure Analysis

In this episode, we will define what structural failure is and discuss how it manifests in materials and designed parts in the form of cracks, pores, etc.

Introduction to Failure Analysis

In this episode, we will start with an introduction to Failure Analysis, an investigational method to identify and understand the root causes of failure for materials and products.
