According to Wohlers Report 2015, a leading 3D printing insights publication, the 3D printing industry grew by a 35.2% year over year in 2014, which translated to $4.1 billion in worldwide revenue. Wohlers also estimates that the 3D printing industry is expected to generate more than $21 billion in worldwide revenue per year by the end of 2020 – an over four-fold increase from 2014 levels.
