Metal clamps are eliminated because of a new spin welding process used in the pressure line of the award-winning diesel exhaust fluid system (DEF) in the 2011 Ford Superduty pickup truck. A 50 percent glass reinforced polyamide quick connector is friction welded to a polyamide line in one of the many technical innovations in the DEF system, which won the Grand Prize at the 40th Annual Automotive Innovation Awards Gala held by the Society of Plastics Engineers International in November. The all PA12 inner tube line construction is 40 percent lighter than competitive EPDM rubber lines, according to Scott Cooper, an engineer with Ford Powertrain Engineering.
Spin welding, a technical strength at Ford, is used to join spherical plastic parts. Generation of friction at the mating surface by spinning one part (upper) against a fixtured (lower) part, fastens the assembly.
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.
Using simulation to guide the drafting process can speed up the design and production of 3D-printed nanostructures, reduce errors, and even make it possible to scale up the structures. Oak Ridge National Laboratory has developed a model that does this.
