Between ExOne's (XONE) stellar IPO and the 2012 gains seen by 3D Systems (DDD) and Stratasys (SSYS), it's clear investors are expecting big things from 3D printers. But low R&D spending could stall the industry's progress, warns Ashlee Vance. Unlike chips or hard drives, there's no guarantee of steady technology advances for printer nozzles and plastic melting. DDD and SSYS respectively spent just 6% and 9% of their 2011 revenue on R&D; Vance is more positive on upstarts such as Shapeways, who are finding ways to significantly cut production and materials costs.
