Today, 3D manufacturing technologies are shown as candidates to replace traditional manufacturing technologies. In this direction, many studies are carried out to reduce the disadvantages of 3D manufacturing technologies. The first few of these disadvantages are; high production cost, slow production speed, and lower strength values of the produced product compared to traditional methods. Increasing or decreasing the printing speed, which is one of the 3d production parameters, appears as a parameter that will directly affect the strength and production costs of the produced product. For this reason, it is important to determine the effects that may occur on the mechanical properties of the product produced by changing the printing speed in terms of choosing the printing speed according to the intended use of the product. In this study, the effect of desktop Fused Deposition Modelling (FDM) 3D printing speed on mechanical properties was investigated. Tensile test samples were produced using Polylactic Acid (PLA) material at seven different printing speeds using two different 3D printers operated without bed heating. The mass, hardness, surface roughness, and porosity values of the produced samples were determined. Fractured surfaces of the samples were analyzed using Scanning electron microscopy (SEM) images. The results show that an increase in the printing speed decreases the mass, the top surface hardness, and the tensile strength and increases the porosity, the arithmetic average roughness of the products produced with both 3D printers.
