Stratasys Ltd reported better-than-expected quarterly results and raised its profit and revenue forecast for the year, driven by strong demand for its 3D printers. The company’s shares jumped as much as 22 percent, putting them among the top percentage gainers on the Nasdaq and helping boost the stock of other 3D printer makers. Stratasys, which traditionally sold industrial printers worth $15,000–$750,000, bought MakerBot last year to offer printers starting at just over $1000. Besides being able to cater to the rising demand for 3D printers at more affordable rates, the acquisition has also helped boost sales of Stratasys’ larger, more expensive printers, Janney Montgomery Scott analyst John Baliotti said.
