Abstract

The inkjet position adjustment method includes the following steps. A three-dimensional digital model is obtained, and a slicing processing is performed on the three-dimensional digital model to generate a layer object having a cross-sectional contour. A normal direction of an object surface corresponding to the layer object is obtained from the three-dimensional digital model. When the normal direction points to a negative direction of a first axis, a surface tilt degree of the object surface corresponding to the layer object is obtained, and an inner-shift amount of an inkjet position of the layer object is calculated according to the surface tilt degree. An inkjet region of the layer object is obtained according to the inner-shift amount and the cross-sectional contour. After controlling a print module to print the layer object, an inkjet module is controlled to inject ink on the layer object according to the inkjet region.

A three dimensional printing apparatus is provided. The three-dimensional printing apparatus includes a tank, a rotatable platform, a light source module and a controller. The rotatable platform is elevatably disposed above the tank, and the light module is disposed under the tank. When the controller controls the rotatable platform elevating to a height along an axis direction, the controller controls the rotatable platform rotating a plurality of rotating angles in sequence around the axis direction and controls the light source module irradiating liquid-formation material, so as to sequentially solidify a plurality of object sections of a single layer object.
