Abstract(s)
Additive manufacturing (AM) is an emerging technology to
create 3D objects layer-by-layer directly from a 3D CAD model. The build
orientation is a critical issue in AM and its optimization will significantly
reduce the building costs and improve object accuracy. This paper aims to
optimize the build orientation problem of a 3D CAD model using a robust
multi-objective approach, taking into account the staircase effect and the
support area characteristics. Thus, themain objective is to obtain a robust
Pareto optimal front, composed of solutions that are not quite sensitive to
perturbations in the variables. In this manner, a set of robust solutions is
presented as alternatives and the decision-maker can identify the compromise
solutions and choose according to his/her preferences.
