ABSTRACT
This chapter presents materials panel of the Shanghai workshop. The machines and materials may be the main concern for the law, which are closely related to the manufacturers and providers. 3D printing principles are based on a digital model, through the addition of materials layer by layer, finally forming a solid model. 3D printing mainly involves three aspects: software, equipment and materials. The development of equipment and software is relatively perfect, and the development of the material is the 3D printing industry. 3D printing manufacturing involves intellectual property (IP) rights—from the composition to the optimisation; the preparation of materials to post-processing technology; and the—3D printing engineering applications. The definition of the law of IP can be summarised as a combination of adjustments of all the social and legal relationships regarded. The development of 3D printing materials also has new features.
