Determination of the effects of process parameters on mechanical properties in rapid prototyping method

Keywords: Rapid prototyping, additive manufacturing methods, 3d printer, mechanical properties. In this study, mechanical tests for tensile and bending specimens manufactured with 3d printer, one of the methods of rapid prototyping, the effects of different production parameters on mechanical properties were investigated. Production parameters are determined by the slicing interface of the 3D printing machine's device, for three different slicing models with Solid, Sparse High Density, Sparse Low Density, the production was carried out at 00, 300, 450 and 750 weaving angles. According to the results, although the raw material is the same, the slicing model has an effect on the mechanical properties of the part, the tensile strength of the parts produced by the low density slicing model is lower, however, the bending strength of the low density parts was found to be more flexible. The effect of the slicing angle on the mechanical properties of the part was determined. In the same slicing model, the pieces produced with different weaving angles and the pieces produced with 00 and 450 product angles give closer results to the raw material's mechanical properties, it was determined that the parts produced in other product angles exhibit lower characteristics. As a result of the study, it was concluded that the selection of the slicing model in the parts to be produced by rapid prototyping method should be determined according to the usage area of the piece.
