| 摘 要： | 熔融堆积成型(FDM)是一种典型的快速成型技术,由于无污染适合办公环境下使用而得到广泛应用。分析了层间应力及翘曲变形产生的原因,并在一定的假设条件下,得出了层间应力的计算公式及其在截平面上的分布情况。建立了翘曲变形的数学模型,讨论了各种工艺参数(层数、扫描线长、成型室温度、层厚等)对翘曲变形量的影响。最后提出了减小翘曲变形的措施。

| Abstract: | Fused deposition modeling(FDM),a representative rapid prototyping technology with no use of toxic materials,has been widely used in offices.The reason of interlayer stress and warpage deformation are analyzed in this paper.Under certain conditions,the calculating formula of interlayer stress and the stress-distributing diagram in cut planes are provided,and the mathematical model for warpage deformation calculation is also established.Besides,the influence of different technical parameters on the deformation,such as the number of deposition layers,section length,chamber temperature and layer thickness,is quantitatively analyzed with measurements provided to minimize deformation. |
