ABSTRACT: Support structures are required in DMLS processes to sustain overhanging parts.These structures
are removed at the end of the building process and they represent a significant waste in terms of material, energy
and time employed for their construction and removal. Furthermore, the use of support structures often causes
low efficiency and poor quality of the finished parts. Consequently, the design and optimization of the orientation
and of the limits of construction without suppor ...
