Of the 3D printing firms, 3D Systems has taken the most lumps in the past two weeks or so. A short-seller report trashing the company hit in the final week of January, and the stock price has continued to slide. ExOne and Voxeljet have seen share prices rise in the past week or so, and that probably accounts for the sharp rise in ExOne’s short interest.
