DESCRIPTION:Alex Ferrer (CIMNE\, Universitat Politècnica de Catatlunya\,
  Barcelona)\nAdditive manufacturing has motivated the development of new c
 onstraints in topology optimization to ensure the manufacturability of opt
 imized designs. This work reviews and compares several important classes o
 f constraints\, considering both density-based and level-set methods. Firs
 t\, the perimeter constraint and its anisotropic extension are discussed a
 s ways to control the complexity of boundaries and the orientation of feat
 ures\, which is relevant for directional manufacturing processes. The over
 hang constraint directly addresses the need to limit unsupported regions\,
  a key issue in layer-by-layer fabrication. Minimum length scale control e
 nsures the elimination of excessively small features that are impractical 
 to fabricate and helps avoid mesh dependency. Connectivity constraints pla
 y a crucial role in guaranteeing that optimized structures remain manufact
 urable and free of disconnected components. In this context\, we propose s
 olving an auxiliary problem that enforces connectivity by penalizing or el
 iminating isolated regions\, thus ensuring structural integrity. Both dens
 ity and level-set formulations are examined\, highlighting how these const
 raints can be integrated and the advantages and limitations of each approa
 ch. The study emphasizes that an appropriate combination of these constrai
 nts is essential to bridge the gap between mathematically optimal designs 
 and physically realizable additive manufacturing components.
