3D modeling printing method

Abstract

The invention provides a three-dimensional model printing method. The printing method comprises a first step of establishing a computer solid model to obtain slice information and keeping a temperature of a modeling chamber between 0 DEG C and 60 DEG C; a second step of printing a UV liquid material and a supporting material by a printing head converted from a common ink-jet printing head controlled by a computer and then lifting the printing head to keep a fixed distance between the printing head and a printing surface, wherein the supporting material is distilled water, deionized water or colorless ink; a third step of printing a second layer of UV layer tablet and a second layer of the supporting material on the first layer; a fourth step of repeating the above steps to prepare every layer and finally manufacturing a three-dimensional object and support; and a fifth step of taking out the model member directly from the supporting mater after the model is finished. In the above method, the printing head of the common ink-jet printer is used as the modeling material and the supporting material; and the supporting material is in no need of cleaning after the model.

Description

technical field [0001] The invention relates to a method for forming a three-dimensional object and a support, in particular to a method for manufacturing a three-dimensional object and a support by using UV ink to print layer by layer. Background technique [0002] Existing printers mainly print text and images on paper, or print on other printing media such as ceramic tiles, cards, stationery, gifts, etc., and print information that is flat rather than three-dimensional. For color printers, the printing The head is connected with a plurality of container boxes containing inks of different colors, and each container box communicates with several nozzle holes on the print head. There is also equipment for making three-dimensional objects, but it takes a long time and requires auxiliary facilities such as molds. There is also rapid prototyping technology, but the equipment is relatively large, and there is no way to achieve desktop, miniaturized, and rapid production of three...

Problems solved by technology

There is also equipment for making three-dimensional objects, but it takes a long time and requires auxiliary facilities such as molds. There is also rapid prototyping technology, but the equipment is relatively large, and there is no way to achieve desktop, miniaturized, and rapid production of three-dimensional objects.

In addition, in the process of forming three-dimensional objects, some suspended places need some materials to support them. Usually, some spray-curable materials such as wax are used, which leads to the need to prepare different materials to make three-dimensional object forming parts. The process of separating the support is very complicated. In addition, since the molding material and the support material are mostly extruded by hot pressing, the overall molding accuracy is not particularly high.
