Terry Wohlers is one of the top market researchers in 3D Printing and Additive Manufacturing. He is predicting 6 Billion in 3D Printing revenues for 2017. If that is the case 3D Printing mainstream adoption must be happening at a quicker pace than previously forecasted. Very interesting for those interested in the consumer side of 3D Printing.
