Autodesk has partnered with a Michigan foundry in a 3D printing proof-of-concept project that resulted in a new magnesium commercial airline seat frame so light it could save an airline more than $200 million in fuel costs.
Autodesk used its Netfabb 3D design software to produce a complex geometric model for a new aircraft passenger seat frame just as strong as a traditional seat, but vastly lighter.
The CAD program created a file used to 3D print in plastic the seat frame, which was then coated in ceramic material and heated to a high temperature to evaporate the inner plastic.
