Three-dimensional colorful article production method

Abstract

The invention provides a manufacturing method of a 3D color article. The method comprises the following steps: acquiring a 2D image of at least one surface of the 3D color article by a digital camera and storing the 2D image in a computer; reconstructing the acquired 2D image into a 3D color model by 3D rendering software; generating a 3D geometry file which comprises 3D elements and a color file which comprises color elements by the 3D color model; converting the 3D geometry file and the color file into a 3D print file which can be identified by a 3D printer; and printing the 3D print file to be the 3D color article by the 3D printer. The manufacturing method is used for fast copying a 3D color article with shorter time and lower cost, and the printed article is very vivid.

Description

technical field [0001] The invention relates to a method for making a three-dimensional colored article, which is used for making a three-dimensional colored article according to a three-dimensional object. Background technique [0002] People or other three-dimensional objects were usually taken with traditional cameras in the past. Recently, digital cameras are used to take two-dimensional pictures of three-dimensional objects. The storage of these digital image information gives people a deeper impression of details and colors, and then Used for later browsing and printing. figure 1 That is to say the process: the digital camera 12 takes one or more two-dimensional pictures of a three-dimensional object 10, and then the digital camera 12 transfers the two-dimensional pictures to the computer 14 through a memory card or a data cable, and the latter transfers the two-dimensional pictures to the computer 14. A color photo 18 is printed out by a printer 16 connected thereto....

Problems solved by technology

The three-dimensional grinding machine 24 reads the geometric text from the three-dimensional digital camera 20, and grinds the outline of the three-dimensional object 26 on the blank 28 through the drill bit 22. Different rapid prototyping systems can be used, such as computer numerical control (CNC) grinding machine, three-dimensional The grinding machine 24 receives the geometric text sent by the three-dimensional digital camera 20 and converts it into a series of rotations of the drill bit 22. The green body 28 is loaded on the three-dimensional grinding machine 24 and can be moved up, down, left, and right by the turning machine 25, so that the drill bit 22 Cutting at an ideal position on the surface of the green body 28, after a period of time, the drill bit 22 cuts the green body 28 into a three-dimensional object 26, and the polished three-dimensional object 26 is captured by the three-dimensional digital camera 20 and converted into geometric text and sent to the three-dimensional grinding Although the polished three-dimensional object 10 is a three-dimensional substitute image of the three-dimensional object 10 after grinding 24, it may lack the color, texture and other partial characteristics of the three-dimensional object 10.

It can be seen from this that it is easy to sculpt a person's face and head outline because it has no problems similar to personal characteristics, but usually it is difficult to sculpt a detailed head, which is time-consuming and expensive

[0005] There is also a method of making three-dimensional objects by taking pictures in different positions to obtain the ratio of each part of the face, eyes, nose, ears, mouth and head. However, multiple techniques are used at the same time to sculpt a person's face and headers are error-prone and time-consuming, inconsistent quality and expensive
