Abstract

Article presents analysis of the influence of infill pattern on 3D printed parts compression properties. Most of the researches from this field covered tensile 3D-printed parts properties, but for some applications compression mechanical properties are far more important. For the analysis of compression strength, 3D-printed specimens were produced by Fused Filament Fabrication (FFF) process from acrylonitrile butadiene styrene (ABS) with different shapes of infill pattern. Testing results showed that honeycomb infill pattern results with the highest compression strength. Unexpected result was the lowest compression strength of gyroid infill pattern, which must be more deeply investigated.
