3D printing, married to traditional metal casting, could reshape manufacturing

A proof-of-concept project could save airlines hundreds of millions of dollars.

What is also unique about Autodesk and Aristo Cast's proof-of-concept project is they not only reduced an airline seat weight with a more sophisticated frame design, but they were able to cast in magnesium -- no simple task.

Typically, aluminum is used for airplane seats, but magnesium is 35% lighter. Autodesk's 3D design optimization resulted in more than half of the weight reduction and the magnesium accounted for the rest, Autodesk claims.

For Aristo Cast, combining a newer technology like 3D printing with proven metal casting techniques could spur new growth in its industry.

"Many foundries are reluctant to invest in additive. We see that as a big mistake. Global competition requires us to up our game. We don't see additive as a threat to our business. On the contrary, we embrace combining the new with the 6000-year-old process of casting to produce the highest-quality parts you can find anywhere," Aristo Cast's CEO, Jack Ziemba, said in a statement. "To us, adopting new techniques like additive manufacturing, when blended with our expertise in casting, is a way forward -- not just for our company but for lots of other foundries in the Midwest."
