Today, 3-dimensional (3D) printers are developing increasingly, and rapid progress is being made to become an alternative to traditional production methods. 3D printers, which produce with the Fused Deposition Modeling (FDM) method, commonly produce by using polymer materials in the form of filament with a diameter of 1.75 mm or 2.85 mm. This study, tensile test specimens were produced using PLA filaments of different diameters (1.75 mm and 2.85 mm) with two different 3D printers. The electricity consumption of 3D printers during the production of tensile test samples was measured. The energy consumed by both 3D printers in producing tensile test specimens was compared. Instead of simultaneously producing a single test sample, it has been determined that the power consumption per test sample will be reduced by producing many test samples together.

In this study, tensile test specimens have been produced using ABS (acrylonitrile butadiene styrene) and PLA (poly-lactic acid) material at different printing speeds (20-40-60-80-100-120-140mm/s) with Ultimaker 2 Extended 3D printer. The effect of printing speed on mechanical properties has been investigated. Masses, hardness and surface roughness of the produced samples have been measured, porosity values have been calculated and tensile test has been performed on the produced samples. After the tensile test, images have been taken by scanning electron microscopy (SEM) from the breaking regions of the broken samples. The mechanical properties of the samples produced with the same parameters with both materials have been compared. As a result; it has been determined that the tensile strength of the samples produced with PLA material are higher than the samples produced with ABS material, and the elongation at break values of the samples produced with ABS material are higher than the samples produced with PLA material.
