Mechanical Behavior of Tension of Multipolymers Through Fused Deposition Modeling

The scientific community focuses on seeking printing parameters that reach the maximum of the mechanical propertiesMechanical properties of polymers. One of the more recent approaches to this type of printing being explored is multimaterialMaterials printing. This work investigates the effects of two printing parameters on the resistance of 3D printed parts: (a) multilayer combination and (b) printing speed. The methodology used for the tensile tests was in accordance with the ASTM D638 standard, and using the multimaterial approach in order to analyze different behaviors in relation to combinations. The materialsMaterials used in the research will be Acrylonitrile Styrene Acrylate), thermoplastic polyurethane and copolyester. The study shows that we can get two different results: a rigid materialMaterials combined with a flexible materialMaterials and a rigid materialMaterials combined with another rigid materialMaterials. It was concluded that the TRITAN filament has greater resistance to maximum tension, and the TPU filament presents greater deformation for a mono-materialMaterials presentation. In the multimaterial presentation, the materialsMaterials maintained their tensile strengthTensile strength in the combination of two rigid materialsMaterials, while in the combination of rigid and flexible materialsMaterials, there was an increase in deformation and lower tensile strengthTensile strength.
