THREE DIMENSIONAL PRINTING APPARATUS AND METHOD FOR CONTROLLING PRINTING HEAD THEREOF

摘要

A three-dimensional printing apparatus and a method for controlling printing head thereof are provided. The method is used for controlling a moving path of a printing head of the three-dimensional printing apparatus and the method includes following steps. The printing head is controlled to form a layer object on a carrying surface according to three-dimensional model information. It is determined whether a cross-section parameter of the layer object is match to a small range condition. If the cross-section parameter of the layer object is match to the small range condition, the printing head is controlled to move toward a first direction far away from layer object according to position information of the layer object. The printing head is controlled to move toward a second direction close to the layer object.

主权项

1. A method for controlling printing head, configured to control a moving path of a printing head of a three dimensional (3D) printing apparatus, and the method for controlling printing head comprising:
controlling the printing head according to 3D model information, so as to form a layer object on a carrying surface; determining whether a cross-section parameter of the layer object is matched to a small range condition; controlling the printing head to move toward a first direction away from the layer object according to position information of the layer object when the cross-section parameter of the layer object is matched to the small range condition; and controlling the printing head to move toward a second direction close to the layer object.
