NEW KENSINGTON, Pa. (AP) — Alcoa has laid off 90 workers at its technical center in western Pennsylvania as it streamlines support infrastructure before splitting its aluminum production business from the production of parts for the automobile and aerospace industries. The cuts come even as Alcoa is spending $60 million to expand its 3-D manufacturing capabilities at the center in Upper Burrell Township, about 30 miles northeast of Pittsburgh. Alcoa says its "core innovation areas" aren't affected by the cuts. The company expects to add about 100 jobs at the technical center by next year as it researches the use of 3-D printers to design and produce components for sale to other industries. The technical center laid off about 50 workers in March. Alcoa is offering severance and outplacement services to the laid off workers.
