Stephens analyst Ben Hearnsberger upgraded voxeljet (VJET) to Overweight from Equal Weight, noting that its shares trade at one of the lowest valuations among public 3D printer system makers despite its "significant" outperformance relative to peers. The company should be able to achieve consensus estimates in the out-year, which should lead to renewed investor interest an improved multiple, contends Hearnsberger, who keeps a $6 price target on voxeljet shares. Other publicly traded 3D printer system makers include 3D Systems (DDD), Stratasys (SSYS) and ExOne (XONE).
