Metal additive manufacturing is so cool in concept but a total PITA in the practice. That's a good write up because it shows that the 'printing' part of things is the easy part. Even so, I don't think it mentioned the fact that the parts themselves shrink and deform as part of the annealing process, so you often need complicated support structures to stop distortion during heat-treat. These then need to be removed with a lot of manual labour.
