Additive Manufacturing 1. Weight of component lowered by approx. 50%. 2. Number of parts decreased from approx. 40 to 2. 3. Post processing costs can be reduced significantly. 4. Complexity for free 1. Original part manufactured using Aluminium. Additively manufactured part produced using IN718 (Nickel-based superalloy). SLM Solutions computed material and labor requirements if original part was manufactured with IN718. Comparative figures based on this study. 2. Part by Lighthinge (EDAG, voestalpine, simufact) 3.
