Abstract

With the development of 3D printing technology, 3D printing has recently been applied to many areas of life including education, healthcare, aerospace, automotive, industrial design and so on. Due to the fact that the benefit of 3D printing is great, 3D printing models are often copied, shared and used several times without charging any copyright fee from the original providers. Besides, user can download 3D weapon models from the Internet and easily print them out without any restriction from the production managers or share them unlimitedly. Moreover, 3D printing models are also attacked by hackers and distributed without agreement from the original providers. Furthermore, certain special models and anti-3D weapon models in 3D printing must be protected against unauthorized users. Therefore, the original providers desire a watermarking algorithm to protect the copyright of 3D printing. In addition, an anti-3D weapon model detection algorithm for safe 3D printing is also necessary to restrict the printing of dangerous 3D weapon in 3D printing industry. Finally, in order to prevent attacks, illegal copying and to ensure that all access is authorized, 3D printing models should be encrypted before being transmitted and stored. In this paper, I would like to present general issues in 3D printing security domain.
