German conglomerate Siemens, Abu Dhabi-based Strata Manufacturing, and Etihad Airways announced they will work together to develop the first 3D-printed parts for aircraft interiors in the Middle East and North Africa. The 3 companies said Monday the partnership aims to leverage additive manufacturing, known as 3D printing, to help airlines improve their designs, and will include making complex parts on demand and manufacturing discontinued parts. Under the partnership, a pilot project will develop 3D printing solutions for aircraft cabin interior products for Etihad. Siemens will consult on the selection of materials, testing, and the preparation of processes. The design team of Etihad Airways Engineering will work to certify the parts, and Strata will manufacture the parts in its factory. <br/>
