Stratasys (SSYS +7.1%) and ExOne (XONE +3.6%) are posting big gains, and 3D Systems (DDD +1.6%) and Proto Labs (PRLB +2.4%) smaller ones, following a favorable CNBC special on the industry's growth prospects.
Among other things, CNBC noted the industry grew 29% last year to $2.2B (per research firm Wohlers), that 3D printing now makes up 28% of additive manufacturing work (up from virtually nothing 10 years ago), and that China plans to spend $242M over 7 years on a 3D printing research initiative.
CNBC also notes there's plenty of competition: about 30 companies sell additive manufacturing systems for industrial use, and European firms such as EOS, Concept Lazer, and Arcam lead the way in the metal printing space.
Shares are rising on what's proving a good day for momentum stocks. Tesla, Green Mountain Coffee, and Chinese Internet stocks are also registering solid gains.
