Three-dimensional printing system and equipment assembly

A three-dimensional printing equipment assembly comprising:

• a) a three-dimensional printing build system comprising:
• a conveyor system adapted to conduct plural build modules;
• plural build modules engaged with the conveyor system, wherein the plural build modules are adapted to receive and temporarily retain powder from a powder layering system;
• and at least one build station comprising:
• 1) at least one powder layering system adapted to form incremental powder layers within at least one of the build modules;
• and 2) at least one printing system adapted to apply a liquid according to a predetermined pattern to incremental powder layers within the at least one of the build modules;
• wherein the conveyor system repeatedly transports the plural build modules from the at least one powder layering system to the at least one printing system to form a three-dimensionally printed bed comprising one or more three-dimensionally printed articles in the plural build modules;
• and the equipment assembly excludes a printing system adapted to apply liquid to the incremental powder layers according to a polar coordinate algorithm.
