What's a reasonable amount of time to wait for machined plastic prototypes? How does one business day sound. That's how long it takes for The Protomold Co.'s new First Cut Prototype division to turn around most parts once you've uploaded your CAD file and placed an order on the First Cut website. Some larger orders may take up to three days. But that's still pretty darn fast. "For the kind of parts we make, no one is faster," says Brad Cleveland, president and CEO of Protomold Inc. For the time being, First Cut's "kind of parts" are plastic, smaller than 10 x 7 x 3 inches, and with geometries capable of being produced on three-axis milling machines. The company can supply parts in a range of plastics–including polycarbonate, ABS, acetal, nylon, polypropylene, high-density and polyethylene. Protomold launched First Cut only a few months ago and has yet to roll out web-based quoting tools as sophisticated and automated as Protomold's ProtoQuote system for injection molded parts. But First Cut is moving in the same direction as Protomold over the coming months, according to Mark Kubicek, First Cut's vice president of operations. He adds that First Cut also has the the potential to expand to larger parts, metals, and five-axis machining in the future.

During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
