Experimental Study of ABS Material Shrinkage and Deformation Based on Fused Deposition Modeling
Department of Manufacturing Engineering ,Shanghai University of Engineering Science, Shanghai, 200437, China
The CAD model can be directly converted into physical model by rapid prototyping , which provides more convenient means for concurrent design in physical verification. However, the deformation of the material shrinkage can cause large deviation of the molding size in CAD model transforming to physical model. In order to ensure the reasonable assembly of the rapid prototyping part, the forming experiment of ABS material was carried out by the principle of FDM. Through regression analysis, a linear relationship with the molding shrinkage and model size was found Meanwhile, deforming mechanism of prototyping parts was analyzed. The rationality of assembly and quality of print parts can be ensured by these law of pre-process.
