3D Systems pre-announced earnings for fiscal year 2013 that will be much lower than it previously expected. 3D Systems also warned that fiscal year 2014 would be lower. The company blamed the reduced earnings on significant R&D costs plus increased manufacturing and marketing costs. Many analysts decided to keep their positive outlook on the company while trimming price targets. However, shareholders weren't as optimistic and sold off 3D Systems and other 3D printing companies.
