The possibility of another 3-D printing company acquisition by Stratasys (NASDAQ:SSYS) seems to be increasing by the day. In a conference call, the company says it is exploring options for entering the metals printing marketplace and recently established a $250 million credit facility. 

These two factors combined could mean further consolidation in the 3-D printing industry, but just who could Stratasys go after? 3D Systems (NYSE:DDD) already purchased Phenix Systems and it doesn't appear Stratasys could afford some of the other larger metal 3-D printing companies like ExOne and EOS. Unless the company produces its own technology, this leaves the company with four viable alternatives: ReaLizer, Layerwise, SLM Solutions, and Concept Laser.
