3D Systems Corporation (NYSE:DDD), considered a bellwether for the 3-D printing market, released preliminary results for 2013 and provided profitability guidance that was below Wall Street estimates.
As previously noted in ValueWalk, the 3-D printing market has been long on hype and industry promise but short on delivery of cost effective solutions in an actual mass production environment. Certain hedge fund professionals have been shorting the stock, led by Dialectic and Whitney Tilson, a fact reported by ValueWalk in December and January.
