Peek through the inspection windows of the nearly 100 three-dimensional (3D) printers quietly making things at RedEye, a company based in Minnesota, and you can catch a glimpse of how factories will work in the future. It is not simply that the machines run day and night【C1】______by just a handful of technicians.【C2】______it is what they are making that shows how this revolutionary production process is【C3】______the manufacturing mainstream. 3D printers make things by building them up, a layer at a time,【C4】______a particular material, rather than【C5】______it by cutting, drilling or machining—which is why the process is also called additive manufacturing. There are many ways in which this can be done, and with only a【C6】______adjustment of software each item can be different,【C7】______the need for costly retooling of machines. This has made 3D printing a【C8】______way to make one-off items, especially prototype parts, mock-ups, small mechanical【C9】______and craft items. And that is about all that 3D printers are good for,【C10】______the doubters. Chief among them is Terry Gou, the boss of Foxconn. He thinks 3D printing is just "a trick" without any【C11】______value in the manufacture of real finished goods, and he has vowed to start spelling his name backwards if【C12】______wrong. Mr. Gou is right about one thing: additive manufacturing is not about to replace mass manufacturing.【C13】______the technology is improving, the finish and durability of some printed items can still【C14】______what producers require. And nor can 3D printers produce millions of【C15】______parts at low cost, as mass-production lines can.【C16】______3D printers have their【C17】______which is why they are starting to be used by some of the world"s biggest manufacturers, such as Airbus, Boeing, GE, Ford and Siemens. The market for 3D printers and【C18】______is small, but growing fast. Last year it was worth $2.2 billion worldwide, up 29% from 2011. As producers become more【C19】______with the technology, they are moving from prototypes to final【C20】______. 【C19】

Could your smartphone prevent a car from hitting you General Motors and other researchers think that"s a possibility【C1】______an emerging wireless standard works its way into the latest smartphones and new cars. First seen in 2010, Wi-Fi Direct【C2】______ultrafast device-to-device connections over the same radio waves that smartphones, computers and other electronics currently use to connect to routers and home networks. The【C3】______here is that unlike your application-enabled television, Wi-Fi Direct doesn"t【C4】______the Internet. Rather, it"s【C5】______connect local devices directly to each other【C6】______as little as a second, and unlike Bluetooth, the connection doesn"t require special pass keys and works at more than double the【C7】______, at about 656 feet apart. GM says future cars could【C8】______pedestrians carrying Wi-Fi Direct smartphones, gather their【C9】______locations and warn the driver through existing active safety systems such as forward collision【C10】______and auto-braking. Wi-Fi Direct is one part of GM"s research on vehicle-to-vehicle and vehicle-to-infrastructure【C11】______in which both cars and roadways become【C12】______aware and adaptive to real-time information. More and more automakers, such as BMW and Hyundai, use a subscription-based 3G cell network to connect a car"s information & entertainment system to the Web for things such as【C13】______searches. A few automakers, such as Ford and Audi,【C14】______wireless hotspots that allow full【C15】______to the Internet from any mobile device. By 2015, Ford said it【C16】______80 percent of the vehicles it sells in North America to have a Wi-Fi connection. Wi-Fi Direct currently allows file【C17】______between two electronic devices【C18】______having to pair them. If the technology becomes popular and【C19】______it could pull the market away from Bluetooth, the short-range wireless standard for in-car telephone calls and portable audio. With Bluetooth, there isn"t one【C20】______way to connect a device—and many times, as we"ve often found, it still doesn"t work. According to data from the National Highway Traffic Safety Administration, nearly 4,900 pedestrians and cyclists were killed by cars last year, for which data were available. 【C19】
