Three-dimensional (3d) object printing based on a build material moisture content level

A method for manufacturing three dimensional objects comprising:

• detecting, for at least one vessel, a moisture content level corresponding to a build material residing in the at least one vessel;
• adjusting a humidity level and/or a temperature of a gas and a conditioning agent applied to the at least one vessel, wherein the humidity level and the temperature are based on the moisture content level and a temperature of the build material residing in the at least one vessel, wherein one or more humidity generators connect to the at least one vessel to provide the conditioning fluid and the gas;
• and
• initializing manufacturing a three dimensional object with the build material from the at least one vessel in response to detecting the moisture content level of the build material residing in the at least one vessel is within a predetermined range.

A three-dimensional printer for manufacturing three dimensional objects comprising:

• a humidifier management system to adjust a humidity level and/or a temperature of a gas and a conditioning agent applied to at least one vessel, wherein the humidity level and the temperature are to be based on a moisture content level and a temperature of build material of the at least one vessel;
• and
• a controller to detect, for the at least one vessel, the moisture content level of the build material of the at least one vessel;
• and initialize manufacturing a three dimensional object with the build material from the at least one vessel.
