This study aims to determine the impact strength of the Fused Deposition Material (FDM) additive manufacturing with the parameters in different layer thicknesses between 0.10 – 0.30 mm. The specimen manufacturing process refers to ASTM D256 Standards with ABS (acrylonitrile butadiene styrene) and PLA (polylactic acid) materials. Based on the test results, ABS specimens with a layer thickness of 0.10 mm had the largest impact strength with 0.078 J/mm2, while the smallest impact strength was found in PLA specimens with a layer thickness of 0.20 mm and 0.30 mm with an impact strength of 0.047 J/mm2. The value of impact strength on ABS and PLA materials varies with each layer thickness change.
