Abstract: The present disclosure provides three-dimensional (3D) printing methods, apparatuses, and systems using, inter alia, a controller that regulates formation of at least one 3D object (e.g., in real time during the 3D printing); and a non-transitory computer-readable medium facilitating the same. For example, a controller that regulates a deformation of at least a portion of the 3D object. The control may be in situ control. The control may be real-time control during the 3D printing process. For example, the control may be during a physical-attribute pulse. The present disclosure provides various methods, apparatuses, systems and software for estimating the fundamental length scale of a melt pool, and for various tools that increase the accuracy of the 3D printing.

Abstract: The present disclosure provides three-dimensional (3D) methods, apparatuses, software (e.g., non-transitory computer readable medium), and systems for the formation of at least one desired 3D object; comprising use of a geometric model, a physics based model, one or more markers, one or more modes, or any combination thereof. The disclosure provides reduction of deformation that may be caused by the forming process of the 3D object.

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.
