Methods and equipment are disclosed relating to three-dimensional printing that include positioning an array of nozzles within a bed of loose solid material, moving the array of nozzles through the bed of loose solid material while injecting a liquid from the array of nozzles in a controlled pattern causing the liquid to react with a portion of the bed of loose solid material forming a solid concrete three-dimensional object. An unreacted portion of the bed of loose solid material may then be separated from the solid three-dimensional object.
