During the construction of an object by layered manufacturing, it might be
necessary to build external supports either to prevent the object from toppling, or to support
floating components and overhanging material. The support structures, if necessary, must
be built simultaneously with the object, and hence must be accounted for in the path
planning of the laser beam or the deposition nozzle. In this paper, we find the best direction
offormation of an object by layered manufacturing process that allows the use of support
structures. In the orientation determined by the best direction offormation, the object is
constructible with a minimal support structure, is stable, and rests on a planar base.
Implementation results are also included.Mechanical Engineerin
