Abstract: The disclosure provides a three-dimensional printing device and a three-dimensional printing method. The device includes a controller, a tank and a printing platform. The controller performs a three-dimensional printing operation according to a slice file, and judges the magnitude of shear force corresponding to a slice object in the slice file to determine a specific rotating angle.
