EFFECT OF PRINTING SPEED ON FDM 3D-PRINTED PLA SAMPLES PRODUCED USING DIFFERENT TWO PRINTERS

Abstract

In this study, tensile test samples were produced using Polylactic Acid material at seven different printing speeds with different two 3D printers without using bed heating. The effect of printing speed on mechanical properties was investigated. The mass, hardness, surface roughness and porosity values of the produced samples were determined. A tensile test was applied to the produced samples. After the tensile test, scanning electron microscope images of the fractured samples were taken from the fracturing regions. The mechanical properties of the samples produced in the same operating parameters on both 3D printers were examined comparatively. As a result, it was determined which printer model used in 3D printing has a significant effect on the mechanical properties of the produced product.
