The Effect of Layer Thickness on Impact Strength Characteristics of ABS and PLA Materials

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.
