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.","lang":"eng"}],"editor":[{"last_name":"Villmer","full_name":"Villmer, Franz-Josef","id":"14290","first_name":"Franz-Josef"},{"first_name":"Elio","full_name":"Padoano, Elio","last_name":"Padoano"}],"date_updated":"2023-03-15T13:49:54Z","year":2016,"user_id":"79260","date_created":"2019-01-22T14:07:32Z","corporate_editor":["Department of Production Engineering and Management  OWL University of Applied Sciences, Lemgo (Germany)","Hochschule Ostwestfalen-Lippe"],"main_file_link":[{"url":"https://www.th-owl.de/elsa/download/333/334/PEM_2016_Proceeding_2016_09_14_Inhaltsnavigation.pdf","open_access":"1"}],"language":[{"iso":"eng"}]}]
