The Mo, Mn and Bronze talked about earlier mentioned have particles using a rough floor, and irregular shapes, which put their flowability in the region of straightforward-flowing. Unusually higher ffc values (Sn, Al powder) are most likely final result from The point that the set normal rigidity is just too little for these supplies. It may possibly for that reason be attributed towards the equipment settings and it needs to be talked about that in these conditions the deformation with the particles can even have an result.
