Well written @hatu, what an interesting concept of 3D printing, especially for concrete.

Yes networking is the key to an online business, it's not what you know but who you know they say. We are not all as lucky as Bill Gates to have a Mom on the inside, getting him a foot in the door. To succeed in this regard there is the story of Steven Spielberg, who became one of the top Hollywood directors by getting in through the "side door", and finding an inside man there to work with. So there is always more than one door to our goal.
