Compression Strength Characteristics of ABS and PLA Materials Affected by Layer Thickness on FDM

Abstract

This study aims to determine the compression strength of the Fused Deposition Material (FDM) additive manufacturing with the parameters in different layer thicknesses between 0.10 – 0.35 mm. The specimen manufacturing process refers to ASTM D695 Standards with ABS (acrylonitrile butadiene styrene) and PLA (polylactic acid) materials. Based on the test results, the highest compression strength is found in 0.15 mm layer thickness PLA material with a yield strength value of 66.78 MPa. The lowest compression strength is found in 0.35 mm of layer thickness ABS material with a yield strength value of 33.41 MPa. The value of compression strength on ABS and PLA materials varies with each layer thickness change.
