Abstract

This study was undertaken to investigate flexural mechanical properties and microstructure effects of three-dimensional (3D) printed thermoplastics including acrylonitrile styrene acrylate (ASA), Polylactic Acid (PLA), and PolyJet material. Test specimens were manufactured using the three-dimensional printing technologies of Fused Deposition Modeling and Liquid Jet employed by four 3D printers. Specimens of rectangular plate shape were printed at a combination of raster angles of 0 degree, 45 degrees, and 90 degrees; orientations of flat and up; and structures with 10% fill and 50% fill. A universal testing machine was employed to determine stress and strain during a 3-point flexural bending test. Modulus of elasticity and flexural strength were determined and compared.
