Abstract

The invention provides a three-dimensional printing method and device. The three-dimensional printing device comprises a printing platform, a printing head, a leveling roller and a controller, and the leveling roller is installed at one side of the printing head in the scanning direction of the printing head. The method comprises the steps that according to layer printing control data, the printing head is controlled to move in the forward direction in the scanning direction and eject materials in a current ejection area, and the printing head is controlled to step one by one in the stepping direction; and meanwhile, the leveling roller is controlled to move in the forward direction in the scanning direction, and materials in the current spraying area and at least one adjacent pass located at one side of the current spraying area are leveled. According to the printing method provided by the embodiment of the invention, the phenomenon of extrusion color crossing generated when the next layer is formed can be avoided, and the flatness and color uniformity of the material layer are ensured.

Description

technical field [0001] The present application relates to the technical field of 3D object forming, in particular to a three-dimensional printing method and equipment. Background technique [0002] In existing 3D inkjet printing equipment, the leveling roller is usually installed on one side of the printing head, and the leveling roller and the printing head move synchronously relative to the printing platform. When the printing method of reciprocating printing is adopted, since the leveling roller is only installed on one side of the print head, the leveling roller will not move when the print head moves forward and reverse along the scanning direction and ejects materials onto the printing platform. The flat rollers level the material of the material layer in one direction only and carry away excess material. Therefore, during the formation of the current material layer, at least part of the excess material on the surface of the pass is not taken away by the leveling roll...
