Abstract
A three-dimensional (3-D) printing apparatus and a three dimensional printing method are provided. The three dimensional printing method includes following steps. A closed printing path of a closed-contour structure is obtained, wherein the closed printing path includes a printing start point and a printing end point. A printing head is controlled to move from the printing start point and along a front segment of the closed printing path according to a first moving speed, and the printing head is controlled to simultaneously extrude a building material. After the printing head moves along the front segment of the closed printing path, the printing head is controlled to move to the printing end point along a rear segment of the closed printing path according to a second moving speed, and the printing head is controlled to simultaneously extrude the building material. The second moving speed is less than the first moving speed.
