On the cover: A Raise 3D printer, listed for $4,000, lays down PETG filament for a dagger­board bearing on a foiling catamaran. Although 3D printing has been used for selective tooling and prototyping jobs, advances in printer technology and feedstock development keep reducing costs while expanding the applications. They now include printing the construction mold of a 34′ (10.4m) power catamaran or the core grid of a Mini 650. Story on page 46.
