In rapid prototyping (RP) technology; prototypes are constructed by the sequential deposition of material layers. When the deposition process involves temperature gradients; thermal stresses will develop. In this paper; the prototype deformation in fused deposition modeling (FDM) processes is studied; and the essence of the deformation and the interacting principles are analyzed. According to basic hypotheses and simplifications; the mathematical model of the prototype warp deformation is constructed; and each of the influencing factors concretely; including the deposition layers number n; the stacking section length L; the chamber temperature T e; and the material linear shrinkage rate α; is quantificationally analyzed. Based on the analysis results; some issues and phenomena in the FDM process are rationally explained. Furthermore; the improving methods for the reduction of the prototype warp deformation are proposed; and the applying effect is better. © 2006 Springer-Verlag London Limited;
