I saw this great video of a rocket engine exploding during a test and discovered this was part of detailed scientific paper which looked at how the defects that destroyed the engine were the result of quality control during the additive manufacturing process. Rather than just repost the video as a short, here's some more detail on the problems in the manufacturing, and the consequences on the test stand.

Here's the paper if you want to go into the microscopic details:
