Object Rotating Subsystem for 3D Printing Circumference Coverage

The patent applies the dynamics principle by making the object rotate during the printing process. Instead of having fixed printheads that can only print within their width, the object rotates to bring different portions of its circumference past the printhead, enabling printing of a circumference much longer than the printhead width. This dynamic approach resolves the contradiction between maintaining simple fixed printhead structure and achieving extended printable circumference coverage.

The patent applies the dimensionality change principle by introducing temporal dimension (rotation over time) to the printing process. Instead of increasing spatial arrangement of printheads vertically, the system uses rotational movement to sequentially present different portions of the object's circumference to the printhead, effectively expanding the printable area through time-based dimension rather than adding more printheads.

The patent applies the universality principle by designing the rotating subsystem to serve multiple functions: it holds the object, rotates it at controlled speeds, positions it accurately for printing, and can pause or adjust rotation during printing. This multi-functional rotating subsystem resolves the contradiction by achieving extended circumference coverage while consolidating multiple functions into a single integrated mechanism rather than requiring separate systems for each function.
