Boeing is making another significant design change to the Dreamliner to accommodate yet another problem that had not been previously disclosed. Boeing ordered suspension of fuselage production at an Italian subcontractor in June when it became apparent small wrinkles were forming in the composite skin. Spokesperson Lori Gunter tells Design News: “We have designed a fix for the barrels that have already been built-a simple patch that is installed from the outside of the airplane. We are completing a permanent fix to the design that will accommodate the changes in the stringer without needing to install a patch-this basically consists of adding a few layers of composites in key areas of the fuselage.”
As reported in Design News, Boeing engineers are also redesigning the area where the wing mounts to the fuselage. The Dreamliner is already two years behind schedule.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
