1. A system for printing a three-dimensional object, the system comprising:
a powder bed configured to receive one or more layers of metal powder;
a vapor generator configured to heat a liquid to form a vapor;
a drying subsystem configured to heat the vapor to produce a dry vapor; and
a vapor deposition subsystem configured to deliver the dry vapor to a surface of the powder bed, wherein at least a portion of the vapor deposition subsystem is moveable relative to the powder bed to deposit the dry vapor.
