Abstract:
One of the many advantages of additive manufacturing is that it doesn't have geometric constraints. It is very common knowledge that additive technology is appropriate to manufacturing parts of very complex shapes, additive manufacturing also gives the designer opportunity to create parts which are optimal in terms of mechanical strength, stiffness, and functionality. For this reason during the design process of components intended to additive manufacturing it is worth using of various shape optimization methods. Methods based on finite element analysis are most prevalent. The connection of additive technology and topology optimization allows creation of optimized parts. Optimal design gives opportunity to reduce the mass of components, increase stiffness and make parts much more cost effective. Additive manufacturing can be also an option for sheet metal parts. It allows creation of thin wall components fitted with integrated stiffeners such as ribs and stringers. Reducing the number of sheet metal parts (consolidation of parts) and increasing stiffness contribute to manufacture of less mass and cost effective aircraft structures.
