Depending on how it’s designed, you might actually not be able to machine it due to inaccessible inner structures. It‘s not exactly time or cost-effective, though.

Maybe in part due to size limitations. The pictures show parts manufactured in a powder bed. The article then goes on to say they‘re still designed around conventional milling. So who knows.

Glad we have FEA, additive manufacturing really wouldn’t be easy to implement without it. I say this because AM is still a rather under-standardised field and will probably remain that way for a while, at least process-wise. Of course you have a general idea of what happens when you change parameters or object geometry, but without simulating things on a case by case basis, no way you would be able to produce a reliable part.
