Not a fan of Motley fool, but buying DDD a few months back has worked out rather well. I look at 3D printing as a potential for a home run but it certainly doesn’t mean it will work out that way. SSYS might be the better play, but it’s hard to say. If you think commercial prototyping is where it’s at then try SSYS. If you think the consumer market is where it’s at try DDD. If you think both are just a bunch of hype kick back and watch it pull off a FSLR, CROX, or NFLX. They aren’t going to look good on paper from a valuation perspective, but early tech growth stocks never do. Is it a QCOM or something we’ll never remember in 2 years.
