  text: "Additive Manufacturing (AM) increasingly enables the realization of structures,
    which have a much greater freedom of design und can therefore better  use  nature
    \ as  a  design  ideal.  Bionic  design  principles  have  already been introduced
    \ into  general  design  approaches,  and  several topology optimization systems
    (TO) are available today to increase structural stiffness and  to  enable  lightweight
    \ design.  AM  and  TO,  used  in  synergy,  promise completely  new  application
    areas. However,  staircase effects resulting from a  layer-by-layer  build  process
    \ and  unavoidable  support  structures  which must be mechanically removed afterwards
    are disadvantageous with respect to surface texture and strength properties.\r\nThe
    present article addresses the question  of how far the notches resulting from
    the staircase effect of Additive Manufacturing and the support structures  removed
    \ decrease  the  strength  of  components.  Most  engineers try  to follow the
    inner flow of forces in a part’s design by smoothening surfaces in notched areas.
    Considering  this,  a  elected component  is investigated  with  finite  element
    \ analysis  (FEA)  with  special  regard  for  the concentration  of  tress arising
    from surface notch effects. An outlook is given as regards how a reduction of
    the notch effect from the taircase effect can be achieved effectively."
