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.
