Abstract

The invention relates to a three-dimensional printing method which comprises the steps that a supporting structure and a three-dimensional object are printed, wherein according to a set printing scheme, the supporting structure and the three-dimensional object are printed through a printing head; and the supporting structure is removed, wherein during printing of the supporting structure and the three-dimensional object, when the distance between the printing head and an object carrying table reaches a set value, a solution which can dissolve supporting materials and cannot dissolve forming materials is used for carrying out ultrasonic cleaning on the three-dimensional object and the supporting structure with the distance from a printing face larger than the set value. During a printing process, the supporting structure is removed, and the printing cycle is effectively shortened. In addition, the invention provides a three-dimensional printing machine suitable for the three-dimensional printing method.

Description

technical field [0001] The invention relates to a rapid prototyping method and a rapid prototyping device suitable for the method, in particular to a three-dimensional printing method and a three-dimensional printer suitable for the printing method. Background technique [0002] A three-dimensional printer is a device based on a digital model that uses materials such as powdered metal or plastic to construct three-dimensional objects by layer-by-layer printing. One of the three-dimensional printers is to supply molding materials to the printing head in the form of filaments, and the molding materials are heated to a molten state by means of electric heating in the printing head. The moving path of the object table is used to print out the three-dimensional object in a layer-by-layer manner. [0003] The background technology of the patent literature with the notification number CN1216726C describes a three-dimensional printer that supplies molding materials to the print hea...
