Özet:

 


Fused deposition modeling (FDM) is one of the
commonly used additive manufacturing methods to produce quality products with
low cost complex geometries with efficient manufacturing and delivery
logistics. Mechanical properties can be improved by examining numerous FDM
parameters and/or using new materials through this method. In this study,
mathematical models have been developed for estimation of some mechanical
properties of parts produced by using PLA+ plastic material by FDM method. For
this purpose, standard tensile and bending test samples were produced with 3D
printer at three different printing speeds and filling ratio with two different
raster angles. The effects of process parameters on tensile and bending
strength were analyzed experimentally and statistically. According to the
experimental results, the importance order of the parameters for mechanical
properties of PLA+ based samples were determined as filling ratio, raster angle
and printing speed. Tensile and bending strengths were higher in samples
produced at 0/90° raster angle. On the other hand, it was determined that the
increase in the printing speed decreased the tensile and bending strength
proportionally. Between the results obtained from the mathematical models
developed with multiple regression analysis and experimental results, an
average deviation of 3% for tensile strength and 2% for bending strength were
found.
