not, this is done using high value materials. This leads to high part production costs which in their final shape_x000D_
would require significantly less material (high buy-to-fly ratio). Additive manufacturing (AM) brings new_x000D_
opportunities in design and manufacturing. One such opportunity comes from AM processes that can add_x000D_

concerns arise from those processes regarding the production of aeronautic critical parts, such as the_x000D_
