Certifying each part is required because the process is "different" enough for each part in AM but I don't believe this is an EB specific problem as equally rigorous certification should apply to all AM processes including laser. Add 6 months to train a technician and 6 months experience for that technician to began producing reliable parts using EB. I don't know if that applies to other processes but in my opinion it should. So many of us on the outside should see why there's a slower spin-up to production than we have anticipated.
So, I'm guessing there's a valid reason for Magnus Rene's tight lips; one shouldn't cause undue hope or alarm in investors about the adoption curve. I believe things are working out like they should but I'm hoping somebody can either: (i) submit a process description that will facilitate certification without loosening standards for mechanical properties or (ii) standardize the build process enough that certification is quicker.
