In this wide-ranging discussion about the latest and next consumer and industrial applications for 3D printing, we examine (with Shapeway's Carine Carmy and a16z's Tom Rikert): how the software-driven ideal of product-market-fit may be achieved in physical products, too -- with rapid prototyping through 3D printing; how the ability to manufacture on-demand changes traditional notions of seasonality and inventory management in product cycles and development; and how the long tail of 3-D printing means being able to have a market of 1.

The modern, average 12-year-old Madden NFL videogame player has actually visualized more plays than ‪any past real-life NFL Hall-of-Famer. And now, for the first time, we're seeing those videogame tactics show up on the field too. There's a "technological and analytical arms race" going on in sports, and it's producing the world's best athletes in history. How are they working smarter, using science and technology to enhance the way they train and perform, when it's not enough to put in 10,000 hours? How should athletes sleep? (Note: you can try this at home, too). And what does “performance by the aggregation of marginal gains” have to do with winning? Author of the new book Faster, Higher, Stronger Wired's Mark McClusky -- interviewed by a16z General Partner (and enthusiastic basketball player) Jeff Jordan -- bridge the worlds of "jocks" and "nerds" in this wide-ranging conversation about sports, performance technology, nature vs. nurture, and the tricky nuances of why some enhancement technologies are legal vs. illegal or better vs. worse than others.
