Multicriteria optimization of 3D printed wing using PLA reinforced with carbon fiber

The purpose of this work is the optimal conception of a wing built using fused deposition modeling (FDM),<br&gtwhich is one of the main additive manufacturing (AM) process. PLA reinforced with carbon fiber was selected for the<br&gtfilament as we have defined their mechanical properties in previous work. The optimization approach use hybrid strategy<br&gtbased on surface response method with kriging model and a heuristic method to avoid to be trapped in local<br&gtminimization/maximization. The objective functions for this optimization are the weight, the drag (functions to minimize)<br&gtand the lift (function to maximize) with respect to the failure criteria of the composite material used…
