Abstract: Provided herein are three-dimensional (3D) printing processes, apparatuses, software, devices, and systems for the production of at least one 3D object printed in a printing cycle, e.g., a 3D printer. The 3D printer describe herein may facilitate safe and accurate printing of 3D objects, e.g., when generated from reactive starting materials. The 3D printer (e.g., comprising a processing chamber, or a build module) may retain a requested (e.g., inert) atmosphere around the material bed and/or 3D object during the printing, e.g., at several 3D printing cycles. The 3D printer may comprise one or more build modules that may have a controller separate from the controller of that of the processing chamber. The 3D printer may comprises a platform that may be automatically constructed. The 3D printing may occur over a long time (e.g., many layers and/or one or more print cycles) without operator intervention and/or down time.
