Problems solved by technology

[0003] The above several processes can make complex three-dimensional structures, but there are the following defects: 1) the precision is low
2) Molding speed is slow
The laminated solid manufacturing process cuts out the outline of each layer by a laser, and then chops the non-solid area of ​​each layer. Therefore, it takes a long time to process thin-walled parts and the material utilization rate is low.
The 3D printing process using powder as the molding material, although the forming speed is faster than the other four processes, it takes a certain amount of time for auxiliary processes such as powder supply and powder spreading before each layer of processing, and the processed 3D structure generally has several thousand layer, the time of the auxiliary process accumulates mor

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 1 , figure 2 As shown, the specific process of making a three-dimensional object by using the layer-by-layer spraying method to make a three-dimensional object is as follows:

[0022] The 3D CAD model of the 3D structure to be processed is designed by a computer with high-speed computing capability, and the 3D CAD model is sliced ​​and layered to form a series of 2D slices. The thickness of each slice can be the same or different, and the thickness of each slice is 1 μm-300 μm. The computer 11 controls each mechanism to perform coordinated movements according to the forming information of each layer. Specifically, when the production starts, the computer 11 sends the processing information of the first layer to the print head control circuit 12, and the print head control circuit 12 drives one or several print heads in the prin...

Abstract

The invention discloses a method for producing three-dimensional matter via plating layer-to-layer, which comprises following steps: building a computer solid model of three-dimensional matter to be sliced and layered; the computer controls the operation of printing injector and injecting UV liquid material according to the molding information of each layer to be solidified via ultraviolet light to form a layer with the same shape and strength of molding information; injecting support material in the non-injected area as support; adhering each layer to produce designed three-dimensional matter; removing filled support material of each layer to attain the three-dimensional matter of said computer solid model. The invention can quickly, reliably, and safely produce complex three-dimensional matter and composite color three-dimensional matter with lower cost. Wherein, the molding material in said invention is innocuous, therefore, the invention can be used in office.

Description

technical field [0001] The invention relates to a method for forming a three-dimensional structure object, in particular to a method for manufacturing a three-dimensional object by layer-by-layer spraying. Background technique [0002] Rapid prototyping technology is a rapid production tool from computer three-dimensional entities to physical entities. It is suitable for the production of prototypes and small batches of functional parts. The materials of the produced parts can be ceramic materials, metal materials, paper, photosensitive resin and other materials. The commonly used processes of rapid prototyping technology include photocuring process, selective laser sintering, fused filament deposition manufacturing, laminated solid manufacturing and three-dimensional printing. [0003] The above several processes can make complicated three-dimensional structures, but there are the following defects: 1) the precision is low. For example, the precision of the three-dimension...
