I looked at the Forbes website but couldn’t find it.
It turns out to be in a Forbes Special Edition....... Get Rich From Obama .....Investment Guide 2013. In the Technology, Manufacturing section. The article is titled Infinite Factory by Hank Greenberg. it is the most recent edition I have.
This is a recent companion article with a video. The article referenced above concerned the company Makerbot but I can’t find it on line. The online library is caled thingaverse and actually contains 25,000 objects to make on the Makerbot replicators
Thanks. I’ll look for it in the bookstore this weekend.
