IMPERIAL — General Electric plans to build a $32 million facility near Pittsburgh International Airport to develop three-dimensional printing and other high-tech manufacturing processes.

The company plans to employ 50 high-tech engineers at the Findlay Township facility, which will break ground in March and should be completed in September.

Three-dimensional printing refers to a process in which digital images are fed into a machine which can “print” — or make — products that correspond to the image out of plastic, metals or other materials. General Electric is already using the process to create fuel nozzles for new jet engine models it is producing.

GE chose the location because Carnegie Mellon University, the University of Pittsburgh and Penn State University all have research programs devoted to 3-D printing.

SAN FRANCISCO — Comcast CEO Brian Roberts says the company is moving “full steam ahead” with its proposed $45 billion acquisition of Time Warner Cable despite the uncertainty raised by President Barack Obama's call for tougher regulations on high-speed Internet service providers.As part of its commitment to getting the Time Warner deal done, Roberts says Comcast still intends to spend about $20 billion during the next two years to improve its Internet service and other products.Roberts' stay-the-course remarks, made during a presentation Wednesday in San Francisco, contrasted with a cautionary statement from AT&T's CEO Randall Stephenson. In earlier appearance at an investment conference, Stephenson said AT&T is scaling back on its spending plans until the Federal Communications Commission determines the new rules governing Internet service providers.
