Sažetak
The paper investigates the influence of the 3D printing process, specifically the orientation of the samples on the basic mechanical properties of PLA polymers. The test specimens were printed from MAKERBOT PLA polymers under the same parameters but in three different build orientations. Analysis of the macrostructure of the samples revealed the appearance of "elephant's foot" phenomenon due of the printing process. The tests included static tensile testing, three-point bending, impact toughness and hardness measurement. The obtained results showed significant deviations depending on the build orientation. The analysis of fracture surfaces demonstrated a large alotment of porosity in the structure, which was most likely one of the causes of such dispersion of the obtained results.
