EXPERIMENTAL INVESTIGATIONS FOR DEVELOPEMENT OF HYBRID FEED STOCK FILAMENT OF FUSED DEPOSITION MODELLING FROM RECYCLED NYLON-TiO2 (70-30%wt.) BLEND by Robin Thakur
Abstract
Fused deposition modeling is one of the established RP processes having ability to produce functional parts with the complex geometrical designs. In the past 20 years lot of work has been carried out on the FDM process. But hitherto no work has been reported for the FDM process on the in house developed FDM filament on the recycled Nyoln-TiO2 (70-30%wt.) blend. In the present work an attempt has been made for controlling the process parameters of twin screw extruder for the in-house production of reinforced Nylon-TiO2 FDM filament. The present research work has been performed on recycled Nylon-TiO2 (70-30%wt.) blend (using twin screw extruder) by considering the three output parameters (temperature of the barrel, rpm of the screw and load applied to the extrusion process). Investigations were performed to check the influence of process parameters on mechanical and metallurgical properties (like: tensile strength, Break strength, Peak load). The results are supported by photomicrographs
