Problems solved by technology

[0003] In the existing technology, the 3D model is usually directly encrypted when it is transmitted. The disadvantage of this method is that it is easy to cause very individual loss or modification of coordinates, indexes and other information in the 3D model, thus affecting the entire 3D printing model. The original shape, and if an error occurs during the encryption process, it will cause an error when converting to G code, which will affect the effect of the final printed model

Abstract

The present application discloses a 3D model encryption method and device. The 3D model encryption method includes: obtaining a 3D model; slicing the 3D model to obtain a G code file; encrypting the G code file and generating a decryption file. Compared with the prior art, the 3D model encryption method of the present invention is more secure and convenient by encrypting the G code.

Description

technical field [0001] The invention relates to the field of 3D model encryption, in particular to a 3D model encryption method, a 3D model decryption method, an encryption device, a decryption device and a 3D model transmission method. Background technique [0002] As an incremental manufacturing technology, 3D printing technology is widely used in the processing and manufacturing industry, and also has broad development prospects in the aerospace, medical equipment and construction industries. With the rise of cloud service platforms, the trend of "Internet +" 3D printing socialization and network services is becoming more and more obvious. Therefore, data protection of online 3D printing manufacturing model is the key to realize intellectual property protection under the online 3D printing manufacturing mode for open crowd creation. [0003] In the prior art, the 3D model is usually encrypted directly when it is transmitted. The disadvantage of this method is that it is ...
