The Boeing 787 Dreamliner has been boom and bust for fastener suppliers. When production of the aircraft first began, a shortage of fasteners slowed the assembly lines. Now, there’s a glut of fasteners in the supply chain. “We probably haven’t seen an order for a fastener on a 787 or a (Airbus) A380 for the better part of two years,” says Bill Christopher, the executive vice president of Alcoa. Distributors bought a large supply of fasteners for the aircraft-essentially on speculation-before the economy nosedived and the 787 encountered design and production problems. It’s now more than three years late but the first delivery is now expected later this year. The A380 also experienced delays. Christopher told analysts in New York last month that he expects normal fastener demand for the aircraft to resume later this year as well. Fasteners are close to a billion dollar business ($868 million in 2010) at Alcoa.
A composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
Microsoft, HP, Dassault, and other industry heavyweights in 3D printing have launched a new 3DP file format, 3MF. The consortium says the spec will more fully describe a 3D model and will be interoperable with multiple applications, platforms, services, and printers.
NASA's been working on several different ongoing projects for 3D-printed rocket engine components in metals and now it's reached another first in aerospace 3D printing: a full-scale, 3D-printed rocket engine component made of copper.
