one conclusion, maybe try EBM instead

The electron beam melting process preheats the entire build platform to just under the melting point of titanium, and so generates much lower thermal gradients?—?and, as a result, less internal stress?—?than DMLS. EBM also generally requires fewer support structures, which is helpful for part cleanup. However, the surface quality and minimum feature size of EBM is significantly worse than DMLS, so EBM would probably require a longer overall process chain, with more material removal than DMLS would.
both DMPLS and EBM have their place. But laser technology is older and better developed so I think EBM has more potential. Especially with all the free research into the physics involved.
