摘要： 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 phenomenon pulse. The present disclosure provides various methods, apparatuses, systems and software for estimating the fundamental length scale of a melt pool.

摘要： The present disclosure provides three-dimensional (3D) printing method and apparatuses 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. An example of a 3D is printer (360), where the radiation (320) is projected from the exposed surface (308) of the material bed (304) towards the ceiling of the enclosure (300) and detected in the sensor part (318). For example, the control may be during a phenomenon pulse.
