would achieve annual fuel savings of 63 tons for an Airbus A380 that holds 615 seats. Based on current costs for jet fuel, average annual savings per aircraft could be $103,324 and life of service savings (20 years) would be over $2 million per plane. A fl eet of 100 aircrafts would achieve annual fuel savings of more than $206 million. “T ere is a huge amount of excite-


ment around these high-performance structures with metal printing, but we see an interesting opportunity for foundry markets to engage in using 3-D techniques for making patterns and molds,” Bastian said. “It shows we can realize the same value from direct metal printing with a technology like


Casting of the Year


Cast Component: Aerospace seat frame. Material: Magnesium. Process: Investment casting. Weight: 1.7 lbs. Dimensions: 17.4 x 17 x 0.8 in. Application: Lightweight seatback frame sup- porting passenger seats in aircraft.


metalcasting that is very well under- stood, very familiar, and off ers a huge portfolio of materials that in many cases are already qualifi ed for aerospace.


T e foundry industry is in an exciting spot to capitalize on the advanced de- sign technologies to realize tremendous value very quickly.” ■
