摘　　要：采用傅里叶变换红外光谱法(FTIR)、拉曼散射光谱法(Raman)对几种国产和进口3D打印用丙烯腈-丁二烯-苯乙烯共聚物(ABS)丝材进行了成分鉴定,分别甄选出了合格及不合格ABS丝材;将合格的ABS样品通过3D熔融沉积快速成型技术(FDM)打印成国标试样,并进行拉伸性能测试,讨论了各ABS丝材在成分、拉伸性能及打印性能上的差异。结果表明:通过FTIR及Raman光谱分析,能够对ABS丝材的质量及成分进行鉴定。几种合格丝材样品中,国产样品C4的拉伸屈服强度最高(43.6 MPa),而进口样品I3具有最低的拉伸屈服强度(33.7 MPa),但丝材I3的打印产品翘曲度小,尺寸精度相对稳定。The components of several domestic and imported acrylonitrile-butadiene-styrene copolymer（ABS） fiber products used for 3D printing were identified by Fourier transform infrared spectroscopy（FTIR） and Raman scattering spectroscopy, and the qualified and unqualified products were distinguished. The tensile tests were carried out on the specimens formed by fused deposition modeling（FDM） technology with qualified ABS fibers. The differences of component, tensile properties and printing properties between these ABS fibers were discussed. The results show that quality and components of ABS fiber products can be identified by FTIR and Raman scattering spectroscopy. Domestic sample C4 has the highest tensile stress at yield（43.6 MPa）, while imported sample I3 has the lowest（33.7 MPa） among all qualified products. But the product made by imported sample I3 has less warpage and its dimensional accuracy is relatively stable.
