A Study on Mechanical Properties of Low-Cost Thermoplastic-Based Materials for Material Extrusion Additive Manufacturing

The present research focused on studying the mechanical properties of three commercially available thermoplastic-based materials used for additive manufacturing (AM) fused filament deposition (FFD) method. scientific motivation study was limited information in literature regarding materials’ properties, inconsistencies that were recorded by other scientists between and technical datasheets anisotropic behavior additively manufactured materials. Thereby, it considered great importance to perform an extensive several such as tensile flexural properties. Three tested, Tough PLA, nGen CF10 UltraFuse PAHT CF15. tests consisted monotonic tests, open-hole three-point bending tests. assisted also with use microscopical investigations. Framed specimens’ configurations two different raster orientations (90°/0° −45°/+45°) using in-house-developed 3D printing equipment. best performances 90°/0° ensured highest tensile, strength, regardless material type, while −45°/+45° elongation values. analysis showed experimental validation AM.
