My $0.02... I could certainly see it bouncing here -- at the 50 DMA, lower Bollinger Band & the nice round number of $10. But it's such a choppy environment that without some catalyst, I wouldn't expect much beyond a retest of the February high.  

All good points, thanks.  I see some catalysts with their recent news releases such as the Baker Hughes deal and in the new capability for customized breast reconstruction after cancer surgery, and I think the additive manufacturing space will grow a lot the next several years.  Normally I trade short-term on technicals, but taking a bet on DDD on funnymentals with a 12 to 36 month timeframe looking for a two-bagger or better.  Also bought some Jan 24 far out of the money call options.
