Rumors of a pending acquisition and a swirl of favorable publicity gave a more-than-5-percent boost to the stock of Stratasys, the 3-D printer company now based in both Eden Prairie and Israel.
The stock closed Monday at $82.65, up $4.17, or 5.3 percent. At one point in early afternoon trading, the stock was up 7 percent.
On Saturday, the online tech news site TechCrunch.com quoted unnamed sources as saying Stratasys, one of the largest companies in its field, was in talks to acquire MakerBot, a New York City-based maker of low-end 3-D printers.
Representatives of Stratasys and MakerBot could not be reached for comment Monday.
The run-up in the stock comes at a time of unprecedented interest in 3-D printing, which holds out the promise of revolutionizing the manufacturing of some everyday objects, such as coffeepots, machine parts and, to the dismay of some, guns, by personal devices that print physical objects by layering deposits of sprayed material.
Stratasys stock likely is benefiting from the large amount of publicity surrounding the potential uses of 3-D printing rather than from the perceived benefits of acquiring a smaller company, said Andy Adams, an analyst at fund manager Mairs and Power in St. Paul, which owns Stratasys shares.
"We met with the Stratasys people two weeks ago, and they're still trying to get their arms around their Objet merger, which was a merger of equals," Adams said in an interview. "I'd be surprised if people were excited about another acquisition right now."
A search for "3-D printing" on Google News produced a page full of enthusiastic headlines claiming the technology is likely to change the future. While some of the possibilities of 3-D printing remain more science fiction than fact, given that the plastic parts generated by 3-D printers are not as durable as their metal counterparts, the technology has found wide applications in industry as a way to rapidly turn around prototypes of new products.
