Terribly sorry about that, pdb2. I confused you with someone else that's not reading carefully. I'm spending hours looking over things carefully before I post so I'm not especially long fused sometimes.
I suspect certification can take a long time but I haven't researched it. Many lives are at stake if a part like this fails so I look at part trials like drug trials. When you read these articles they reinforce the idea that these are like one experiment after another. It just takes time.
I can't remember where I read this, maybe the GKN link that Charlie Colton posted, that EB methods produce a better part at 25% savings. ORNL concluded a 50% savings in their 2013 publication. I'm sure others will come up with other results.
Like you, I believe this to be a fine technology that was developed carefully with educated minds looking carefully at metallurgical qualities. Now that we see Arcam is getting certification for some parts, that the technology has cost and time saving benefits, I'm sold. I'm just getting quickly weary with those that get jumpy at every announcement of a competing technology.
