The present disclosure provides three-dimensional (3D) printing methods, apparatuses, systems and/or software to form one or more three-dimensional objects, some of which may be complex. The three-dimensional objects may be formed by three-dimensional printing using one or more methodologies. In some embodiments, the three-dimensional object may comprise an overhang portion, such as a cavity ceiling, with diminished deformation and/or auxiliary support structures.

The 3D printer system (e.g., comprising a processing chamber, build module, or an unpacking station) described herein may retain a desired (e.g., inert) atmosphere around the material bed and/or 3D object at multiple 3D printing stages. The 3D printer described herein comprises one or more build modules that may have a controller separate from the controller of the processing chamber. The 3D printer described herein comprises a platform that may be automatically constructed. The invention(s) described herein may allow the 3D printing process to occur for a long time without operator intervention and/or down time.
