Abstract: The present disclosure relates to generation of forming instructions to form one or more three-dimensional (3D) objects. Generation of the forming instructions may include selection of one or more formation variables to form at least a portion of the one or more 3D objects. Generation of the forming instructions may include selection of a speed, feature, and/or an effect manifested in at least a portion of the formed one or more 3D objects. The forming variable(s) may be associated with a patch of a model of the 3D object.

Abstract: 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.

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.
