On processing of PVC-PP-Hap Thermoplastic Composite Filaments For 3D Printing In Biomedical Applications

摘要

Additive manufacturing (AM) or 3D printing technology is one of the fastgrowing fabrication processes in different manufacturing sectors. For 3DP, by using the fused deposition modeling (FDM) process, feedstock filament is to be used as input materials for the fabrication of any model, scaffolds, or any other things. In this research work, feedstock filament has been fabricated by reinforcement of hydroxyapatite (HAp) powder in PVC and PP thermoplastic polymers by using twinscrew extruder (TSE) based upon Taguchi L18 orthogonal array (OA). After the fabrication of feedstock filament using TSE, tensile testing has been performed on a universal tensile tester (UTT). The modulus of toughness has been calculated using output values from tensile testing. In this experimental research work, the best input setting of the extruder for the preparation of feedstock filament is to be obtained using Taguchi L18 OA, and on best setting confirmatory experimentation has been performed. Finally, based upon this experimental work shows the best parametric conditions for modulus of toughness have obtained at the parametric combination of 96Q 4, 50rpm, 200°C, 106 μm, and 20 kg load.
