Abstract

In this study, flexural properties of 3D printed
PLA beam specimens produced with different filling ratios, orientations and
print temperatures are experimentally investigated. Various bending specimens
were produced by means of 3D printer using PLA filament as raw material. Low,
intermediate and high filling ratios, lengthwise/widthwise and crosswise
filling orientations, and different print temperatures were chosen as
alternative production parameters of the printer. Manufactured beam specimens
were subjected to three-point bending tests at room temperature in accordance
with the TS EN ISO 178 standard. Effects of production parameters on mechanical
bending properties including flexural modulus, maximum flexural stress,
flexural strain at break, maximum force, and maximum deflection are clearly
shown and discussed to state reasonable explanations of test results and to
make conclusive suggestions.
