Chris Anderson: “The BotCave is home to MakerBot, a company that for nearly four years has been bringing affordable 3-D printers to the masses. But nothing MakerBot has ever built looks like the new printer these workers are currently constructing. 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.”
