摘要: 以熔融堆积成型过程中原型的变形为研究对象,分析变形产生的根源及其作用机理,建立了成型过程中原型的翘曲变形模型,并定量地分析了各种因素,包括堆积层数、断面长度、环境温度和材料的线收缩率对原型变形的影响程度。分析结果合理地解释了熔融挤出堆积成型过程中的一些现象,据此提出了减小原型翘曲变形的相应措施,实际应用效果较好。

Abstract: The prototype deformation in FDM process is studied, and the essence of deformation and interacting principle are analyzed. According to some reasonable hypothesis, the mathematic model of prototype warp deformation is founded, and each of the influencing factors, including deposition layer number, section length, environ- mental temperature of chamber, and material linear shrinkage rate, is quantitatively analyzed. Based on the analyzing results, some issues in the process of FDM are rationally explained. Furthermore, improvement methods for the decrease of warp deformation of prototype are provided, and the applying effects are better.

Key words: Fused deposition modeling, Rapid prototyping, Warp deformation
