FARMINGTON, Conn. - As part of a multimillion-dollar expansion plan, Trumpf Inc. will build a laser research, development, manufacturing and demonstration facility in Farmington, Conn.

To meet increasing demand for industrial lasers, the new factory will produce lasers for cutting, welding and marking sheet metal, and other materials. The planning for the new 30,000- to 40,000-square-foot building has already begun and is expected to take 12 months to complete.

The company will also invest in capital machinery for existing production facilities and increase its focus on advanced laser technology and more sophisticated manufacturing in Connecticut.

"Our goal is to keep, and grow, next-generation laser manufacturing and development here," said Rolf Biekert, president and CEO of Trumpf Inc. "The increased focus on laser technology will help us to better serve the needs of U.S. customers."

Last year, the company had a nearly 30 percent increase in U.S. sales for its lasers business. In addition, over the last three years, Trumpf Inc. has spent close to $40 million on U.S. research and development efforts, officials said.
