I'm not sure I made a blanket statement, except with respect to my understanding, and I can assure you that I was factually correct in my assessment of my own understanding. ;)
I was careful to phrase my comment in a way that I thought could lead to useful discussion, because I value that, and to note it was only my understanding, because my understanding is outdated and minimal. It just so happens that I was part of a prior discussion years ago regarding suitability of 3d printed metal parts, and found some information at that time which pointed to some of the problems they have in comparison to other methods, so was interesting in learning more.
