I thought some of you might be interested: I had a recent conversation with @Brook_Drumm2 of Printrbot. We talk about how he got started, scaling up, his hot end, how he sees the big guys entering the market, 3D printing in education and few other things.
It was a fun talk with a really good guy. Enjoy!
