3D Printing is one of the most exciting forms of technology in generations. Why? The potential is boundless. So while tapping 3D technology holds much promise for the jewelry, medical, and prototyping sectors, what I find most exciting is the role 3D printing can actually play in energy. For instance, think of the cost savings potential for cutting time and material waste when producing solar panels. So while names like 3D Systems (NYSE:DDD) and Stratasys (NASDAQ:SSYS) continue to turn investor heads, I'm intrigued by the potential for both Xerox (NYSE:XRX) and even DuPont (NYSE:DD) to being considered alernative energy plays.
