Rather than creating physical prototypes and sending them halfway around the world for review and evaluation, some companies are drastically cutting development cycles by transmitting merely the electronic data describing the physical product. A 3D prototype is then created at the receiver's end. Coined "3D faxing," this process is growing in popularity among engineering groups, says Marina Hatsopoulos, CEO of Z Corporation, whose 3D printing technology fabricates physical 3D models directly from a computer file. Among companies that plan to use 3D faxing is Motorola, who currently uses Z-Corp.'s rapid prototyping technology for cell phone design work. Hatsopoulos describes a major consumer products company that makes strollers and car seats who recently jumped on the 3D faxing bandwagon: "Engineers e-mail their CAD files to a production facility in Asia, where the design is 'printed' and the physical part is reviewed for manufacturability. The Asian production group adds any changes to the design, and emails it back to the U.S. for printing and review." Major benefits? Rapid feedback and the ability to do iterative design collaboration.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
