Abstract: 3D printing is a superior manufacturing technology developing rapidly in recent years and will be a key link in the high-end manufacturing area of the strategic initiative industry 4.0 （known as Industry 4.0）. Despite of this, the supply form of 3D printing materials is far less optimistic. To quicken the localization of 3D printing materials, we used GC-MS technology to analyze the printing ink and the organic compositions of the cleaning agent in 3D printing materials. Specifically, we identified organic ingredients and their relative percentages in the printing ink and cleaning agents based on the total ion chromatogram obtained, analyzed the pirnting mechanism of the printing ink and the cleaning mechanism of the cleaning agent, and verified the repeatability and accuracy of the data were verified, eventually having a better understanding of the components of 3D printing materials. The experiment is significant in accelerating the production of 3D printing materials in China and also conductive to the fusion of 3D printing materials with Industry 4.0 in China.
