I want to hear about what the contaminant was. I saw in another article that these are additive manufactured parts; they take powder metal, use a laser to fuse it together, and 3D print the parts building up layer by layer. Any extra metal powder is collected, sent to a company for cleaning/testing/certifying and then recycled through to use in the printers again.

So was the contaminant there from the beginning or was it introduced into the powder at some point as it cycled through? What does their readacross look like; are there other parts out there that potentially have similar contamination? I hope they eventually disclose way more detail and progreas as the investigation continues.
