Provided herein are methods, apparatuses, and non-transitory computer readable media concerning quality assurance of three-dimensional object(s) and their formation. In some embodiments, a plurality of variables is considered in assessing performance of a manufacturing mechanism (e.g., printer) utilized in forming the three-dimensional object(s). In some embodiments, a plurality of variables is considered in assessing a process for forming the three-dimensional object(s). In some embodiments, a plurality of variables is considered in assessing a quality of the formed three-dimensional object(s).

Quality assurance in formation of three-dimensional objects

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.

Accurate three-dimensional printing

The present disclosure provides three-dimensional (3D) printing methods, apparatuses, systems, and non-transitory computer-readable medium. The disclosure delineates real time manipulation of three-dimensional printing to reduce deformation. The present disclosure further provides 3D object formed using the methods, apparatuses, and systems.

Adept three-dimensional printing

Three-dimensional printing in real time

A system and method are described for aligning a data axis of one or more circular data-bearing tracks on an annular surface region of a magnetic media-bearing disk, with a spin axis of a spindle of a spinstand or a disk drive. The data axis is perpendicular to the surface region of the disk and the data tracks are concentric with respect to a data axis.
