CHANGE: The New MakerBot Replicator Might Just Change Your World.

The Replicator 2 isn’t a kit; it doesn’t require a weekend of wrestling with software that makes Linux look easy. Instead, it’s driven by a simple desktop application, and it will allow you to turn CAD files into physical things as easily as printing a photo. The entry-level Replicator 2, priced at $2,199, is for generating objects up to 11 by 6 inches in an ecofriendly material; the higher-end Replicator 2X, which costs $2,799, can produce only smaller items, up to 9 by 6 inches, but it has dual heads that let it print more sophisticated objects. With these two machines, MakerBot is putting down a multimillion-dollar wager that 3-D printing has hit its mainstream moment.

Unlike the jerry-built contraptions of the past, the Replicator 2s are sleek, metal, and stylish: MakerBot CEO Bre Pettis likens the design to “Darth Vader driving Knight Rider’s KITT car while being airlifted by a Nighthawk spy plane.” There is also the lighting. Oh, the lighting. “LEDs are part of our core values as a company,” Pettis jokes. The new machine will glow in any hue—”to match the color of your couch,” he says, “or like something in the movie Tron.”

You’ve heard of 3-D printers, but you probably don’t own one yet. Pettis thinks the Replicator 2 will change that.

Sounds like this is the Altair 8800 of 3D printers. So learn from my missed opportunity.

THE GROWTH OF “CHI RUNNING:” “Chi Running evolved when a tai chi-practicing ultra-marathoner decided to apply principles from the Chinese system of slow, smooth movement to his running. The resulting method, which enthusiasts hail as effortless and injury-free, is as specific in form as it is insistent on going with the flow.”
