| 摘 要： | 熔融沉积(FDM)技术是目前市售3D打印机应用最广泛的材料成型技术，基于这一技术的3D打印机精确度评价与打印试件的误差分析还没有十分完善的标准化方法。FDM 3D打印常用的聚合物材料在太赫兹波段存在明显吸收。基于太赫兹时域光谱(THz-TDS)，通过缝隙注水的方式放大试件非实体部分的太赫兹响应，使得太赫兹技术可同时监测3D打印试件实体部分与非实体部分的打印精确度。通过分析试件的太赫兹光谱，能够分辨与原始设计相差0.96%的微米级误差，补充了3D打印误差的分析方法。

| Abstract: | Fused Deposition Modeling(FDM) is a most widely applied material forming technology for 3D printer. Nevertheless, there is no standardized method for error analysis of 3D printing based on FDM. Polymer materials commonly used in FDM has a strong absorption in terahertz range. Using the method of injecting water into the apertures of specimens, error analysis of both the physical area and non-physical area of specimens is successfully realized by Terahertz Time Domain Spectroscopy(THz-TDS). Based on the analysis of terahertz spectrum, the micron error of 0.96% is able to be observed. |
