The Motley Fool's industrial analyst, Isaac Pino, recently attended The Atlantic magazine's Manufacturing Summit for insight into the industry and visited General Electric's (GE 0.68%) 30 Rockefeller offices for a closer look at the $250 billion conglomerate. Isaac and Motley Fool Money host Chris Hill weigh in on the company's transformation over the past few years, its game-changing investments in 3-D printing and the industrial Internet, and the opportunity ahead for GE shareholders.

In the following segment, Isaac answers whether he's bullish on 3-D printing stocks as an investor. He tells us that while the industry itself is fascinating and sure to produce some incredibly creative innovations over the next decade or so, picking one company that's going to emerge as the clear winner from this nascent industry is going to be difficult at this stage.
