Dimensional accuracy and experimental investigation on tensile behavior of various 3D printed materials

Abstract

Additive manufacturing (AM) or 3D printing is becoming very popular in the aerospace and defense industry because of its ability to manufacture complex parts at a low price. Fused deposition modeling (FDM) is one of the most popular 3D printing techniques currently on the market. Acrylonitrile butadiene styrene (ABS) or poly (lactic acid) (PLA) are the two most commonly used 3D printed materials. Dimensional accuracy of FDM processed 3D printed materials (PLA, ABS, PETG, and HIPS) and experimental investigation of the tensile properties of those materials is the main scope of this paper. Tensile testing machine SHIMADZU AGS-X 100 kN was used to carry out the experimental study.
