Luxury car manufacturer Porsche has introduced a new concept for sports car seating that leverages 3D printing and lattice design. The seating concept, called “3D-printed bodyform full-bucket seat,” enables customers to personalize their seat for comfort and is partly inspired by seat fittings designed for professional motorsports.While to many the outside of a car and what’s under the hood are the most important factors when choosing a car, comfort is also a crucial concern. For high-performance cars especially, the driver’s seat is plays an important role in that it can influence the driver’s handling of the car.As Michael Steiner, Member of the Executive Board for Research and Development at Porsche, explained: “The seat is the interface between the human and the vehicle, and is thus im...

Ionizing radiation can cause critical issues for electronic gadgets. To ensure against this, devices that might be presented to radiation -, for example, devices utilized in the shuttle – incorporate radiation shielding.Weight is a significant factor in designing aerospace technologies, and the shielding most commonly found in aerospace devices consists of putting an aluminum box around any sensitive technologies. This has been viewed as providing the best tradeoff between a shield’s weight and the protection it provides.By mixing metal powder- rust — into a polymer, and then incorporating it ...

Cold spray technology, which has been used for decades as a coating process, can be used as a metal additive manufacturing process to rapidly print near-net-shape parts.Cold spray uses pressurized carrier gas to accelerate metal powders to high velocities through a de Laval nozzle aimed at the point of deposition. When the metal powder particles collide with the part’s surface, the high kinetic energy causes plastic deformation, creating mechanical interlocking and metallurgical bonding. Heat is generated during this interaction, but not enough to melt the material. This unique attribute of co...

Shipments of industrial-class 3D printers (priced above $100,000) were up by more than 8% in Q3 2019 compared with the same period the previous year, according to market intelligence from Context (London). This key sector, which accounted for almost 70% of all 3D printer revenues for the period, saw even more impressive shipment growth of 12% on a trailing 12-month basis.“The increase came as a surprise, given the headwinds many vendors reported in the second half of the year, such as reduced demand from the struggling automotive sector, sluggish European economies and a generally weak global ...

Researchers at RMIT have found that sound vibrations can improve the micro-structure of 3D printed alloys.The team used high frequency sound waves to make the alloys more consistent and stronger than those printed conventionally. Lead author, Carmelo Todaro, highlighted that the method deals with inconsistencies in 3D printed alloys.“If you look at the microscopic structure of 3D printed alloys, they’re often made up of large and elongated crystals,” Todaro explained.“This can make them less acceptable for engineering applications due to their lower mechanical performance and increased tendenc...
