Abstract: The laminated object manufacturing is a representative
rapid prototyping technology. The interlaminar stress and warpage
deformation of LOM are researched and analyzed deeply. A simplify model
is proposed to describe the adhesive process and the calculation
formulae of interlaminar stress are deduced by means of analyzing the
model. Based on the experiment results, two kinds of main forms of
warpage deformation are presented. It is the first time that a
describing model of warpage deformation process is presented and it is
believed that equivalent moment caused by interlaminar stress is the
primary reason of warpage deformation. Improvement methods for decrease
of stress and deformation of prototypes are provided.
Key words: Rapid prototyping Laminated object manufacturing
