Fused filament fabrication is one of the most popular technologies of additive manufacturing. The most commonly used materials in this technology are polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS). Even though the usage of polylactic acid in additive manufacturing is already extremely wide, there are still not many researches made on the influences of entering parameters of fused filament fabrication on compression properties of the exact material (yield strength, compression strength at h/2 height of the test piece and modulus of elasticity). The compression properties of the material are determined with compression tests. Systematically it is useful to plan and execute the experiment by itself and analyse the obtained data by the Taguchi method. From the statistical data we can conclude that the entering parameters of printing with fused filament fabrication that gives us the longest times of printing the samples, are still the best option (layer heights of 0,1 mm, speed of printing is 50 mm/s and nozzle temperature of 195 °C).
