Maine Public’s biggest story of year: record-setting 3D printer, boat 

A University of Maine time lapse video of a 25-foot, 5,000-pound boat being printed by a 3D printer at the University of Maine Advanced Structures and Composites Center was Maine Public’s biggest story of 2019 based on traffic volume. The Composites Center earned three Guinness World Records — for the largest printer, the largest solid 3D-printed object and the largest 3D-printed boat.
