气质联用技术在3D打印材料国产化中的应用

GC-MS technology in localization of 3D printing materials

为推进3D打印材料的国产化进程,采用气质联用技术分析3D打印材料中打印墨水和清洗剂的有机成分。通过总离子流图确定打印墨水和清洗剂的有机成分及其相对百分含量,对打印墨水的打印机理与清洗剂的清洗机理进行分析和讨论,并验证数据的重复性和准确性,深化对3D打印材料组分的认识。对推动该打印材料国产化进程具有实际意义,促进我国3D打印材料与工业4.0的融合。

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.
