Modelling Process

In the recent past, various studies have been reported on the development of in-house fused deposition modelling (FDM) filament, in order to increase the application domain of the process. But hitherto very less have reported on the effect of reinforcement type (such as: SiC, Al2O3 and Fe powder etc.) on the melt flow index (MFI) of the polymer matrix composite (PMC) to be used as FDM filament. In the present research work, an effort has beenmade to investigate the effect of selected proportions of filler, matrix (nylon-6) and extrusion load on the MFI of reinforced FDM filament. Experimental study was conducted on melt flow indexer (MFIer) as per ASTM-D1238-95 standard and signal to noise ratio was calculated to find out the effect of input process parameters on MFI of hybrid filament. It has been found that proportion of filler in matrix, type of filler material and extrusion load contributed about 16.62%, 1.23% and 76.72% respectively.

Input Variables

In this experimental study, a composite of poly-ether-ketone-ketone by reinforcement of hydroxyapatite and chitosan has been prepared for possible applications as orthopaedic scaffolds. Initially, different weight percentages of hydroxyapatite and chitosan were reinforced in the poly-ether-ketone-ketone matrix and tested for melt flow index in order to check the flowability of different compositions/proportions. Suitable compositions revealed by the melt flow index test were then taken forward for the extrusion of filament required for fused deposition modelling. For thermomechanical investigations, Taguchi-based design of experiments has been used with input variables in the extrusion process as follows: temperature, load applied and different composition/proportions. The specimens in the form of feedstock filament produced by the extrusion process were made to undergo tensile testing. The specimens were also inspected by differential scanning calorimetry and photomicrographs. Finally, the specimen showing the best performance from the thermomechanical viewpoint has been selected to extrude the filament for the fused deposition modelling process.
