Abstract

See full text

A 3-D printer scalable to large sizes employs a combination of mechanical and electrical scanning of a linear array of electron beams that operate to melt material of a powder bed. A housing holding the electron beam sources may be maintained at a high vacuum and positioned close to a print surface to minimize electron travel in a softer vacuum surrounding a print bed.
