Problems solved by technology

[0004] The types of existing support materials can be divided into: support materials removed by mechanical force, water-soluble support materials, water-swellable support materials, and alkali-soluble support materials according to the removal method of the support structure; among them, support materials removed by mechanical force During the removal of the support structure, the target object may be damaged due to the impact of mechanical force, and the support structure in the fine pore structure is difficult to remove; among them, the dissolution and swelling rates of water-soluble support materials and water-swellable support materials in water are slow , especially when the volume of the support structure is large, the removal rate of the support structure is slow; among them, during the removal process of the support structure, the alkali-soluble support material quickly reaches saturation with the prolongation of time, and the removal rate of the support structure slows down , so the alkaline solution needs to be replaced frequently
It can be seen that the removal efficiency of the existing support structure is low and the processing cost is high

Abstract

The invention provides a three-dimensional object and a printing method and printing device thereof. The method comprises the steps of carrying out the printing in a solid structure region through employing at least one solid material according to slice layer printing data, and carrying out the printing in a supporting structure region through employing at least one supporting material; and solidifying at least part of the solid material of the solid structure region and the supporting material of the supporting structure region to form a layer printing result, wherein the supporting structurearea of the layer printing result is provided with holes. According to the three-dimensional object, when the three-dimensional object is soaked in liquid such as water, a water-based solution or analkaline solution, the liquid enters the supporting structure through the holes, so that the dissolution or swelling rate of the supporting structure is increased, the removal efficiency of the supporting structure is improved, and the treatment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of 3D object forming, in particular to a three-dimensional object and its printing method and printing device. Background technique [0002] 3D prototyping technology is also called rapid prototyping technology, or rapid prototyping technology, or additive manufacturing technology. Its basic principle is to slice the 3D model based on the slicing software, and the data processor converts the slicing data of the model into layer printing data. The controller controls the printing device to print layer by layer according to the layer printing data, and superimpose to form a three-dimensional object. [0003] When printing an object with a suspended structure, the suspended part under the suspended structure needs to print a support structure so that the target object can be formed; after the target object is formed, the support structure needs to be removed from the target object without affecting the surface ...
