Aircraft seat support bears 1.5 tons of load. The original part is made from aluminum and weighs 400g. We’ve anisoprinted a new part on Composer A4 3D printer with a 40% weight reduction.
With 100 such seat supports in an average single-aisle passenger plane, this weight reduction can add up to saving 25 kg per plane. In such fields as aerospace every kilo matters because it becomes costs the company spends during using the aircraft. Cost of fuel for every kilo in an airplane is $2000 a year. Thus we save $50 000 a year per plane.
