The present research is focused on extruding a filament from the blended virgin and recycled PET material and producing specimens by 3D printing and testing them for mechanical properties. Different combinations of blending are arrived from the design of experiments and filament of 1.75mm diameter is extruded for variety of blends. Specimens for tensile test are prepared as per ISO-527, equivalent of ASTM-D3039, compressive test specimens as per ISO-604, equivalent of ASTM-D695, flexural test specimens as per ISO 178:2019, equivalent of ASTM-D790 and the water absorption test specimens as per ISO 62:2008, equivalent of ASTM-D570. In this study the design of experiment shows 15 possible combination of blends but 7 of them chosen because of the repeated value of combination so that (100-0), (75-25), (65-35), (50-50), (35-65), (25-75), (0-100) weight percentage of vPET and rPET are used. The test results show that the tensile stress reduces from 33.57 MPa for 100% virgin to 32.13 MPa for (75-25) recycled blend. For the values of tensile strength for blends are 31.64, 30.41, 28.99, 28.30, and 26.8 MPa respectively. Similarly, the values of compressive strength are 52.73, 51.27, 49.23, 48.47, 46.73, 46.07 and 45.17 MPa respectively for (100-0), (65-35), (50-50), (35-65), (25-75) and (0-100) vPET/rPET blends. The flexural strength values are 67.7, 65.3, 64.23, 61.2, 56.1, 50.4 and 48.73 MPa respectively for (100-0), (65-35), (50-50), (35-65), (25-75) and (0-100) vPET/rPET blends. The results of this study show that the (75-25) blend has reasonably good strength values compared to other types which drives us to choose for producing useful products, preventing atmospheric pollution.
