Analysis Of Copyright Problems In 3D Printing

3D printing technology as a new technology is likely to subvert the traditional manufacturing mode of production in recent years,at home and abroad much attention.On the one hand,3D printing technology is changing the focus,the scale of the traditional mode of production;on the other hand,the technology also makes it easier to manufacture infringing products,resulting in more intellectual property disputes.In the United Kingdom and the United States and other advanced 3D printing technology and the degree of copyright protection is more perfect,there has been a dispute on 3D printing infringement.Although China has not yet appeared in the dispute,but 3D printing in China's rapid development in the near future is likely to occur,and more common in the field of copyright.Due to the 3D printing technology is a new technology,China's legal circles on the technology caused by the lack of copyright research.The copyright system of our country has no clear stipulation on the copyright and the type of work involved in the process of 3D printing,and the attitude of "different dimension copy" is ambiguous.In this paper,combined with the 3D printing process,we hope to clear the scope of copyright law in China,in particular,the right to make certain restrictions on the use of.To improve the copyright system in China,so as to better protect the rights and interests of the rights holders,and thus can better promote the development of 3D printing technology.The first part discusses the classification and principle of 3D printing technology,and the development status and prospect at home and abroad.At the same time,a detailed description of the 3D printing process,can be divided into 3 stages: the data source(which can be subdivided into model design and slicing),printing,post-processing.There are 3 ways to access the data source.Each of these ways to capture the data source will affect the quality of the copyright object.The second part discusses the problems of 3D printing technology to the current copyright system.The object,content and limitation of rights.First of all,the copyright law does not specify the 3D data model and the object type of the 3D print,and according to the different 3D printing process,the 3D data model and the object of the 3D print are also different.Secondly,3D printing is the most involved in the plane to the three-dimensional copy,and China's copyright system on the concept of "copy".Finally,the biggest impact of 3D printing on the copyright system is the problem of private copying.The third part discusses the qualitative analysis of the 3D printing object under the copyright law.First of all,the author analyzes the copyright and the type of 3D digital model from the perspective of originality.Secondly,the relationship between 3D print and 3D digital model is analyzed.Finally,the paper introduces the reparability theory to define the practical art.The fourth part puts forward the suggestion of perfecting copyright system.First of all,it is necessary to broaden the scope of the right to copy,the "different dimension copy" into the scope of replication;secondly,the introduction of the four criteria of rational use;finally,the introduction of CC knowledge sharing agreement and copyright compensation system.
