On the optimal design of metal matrix composites as functionally graded innovative materials for sensor devices

In the present work an effort has been made to prepare Al matrix composite by 3D printing assisted rapid investment casting (RIC). The RIC has been performed by using patterns prepared by fused deposition modelling (FDM). For preparation of 3D parts, a composite material reinforced with ceramic particles (SiC and Al2O3) has been used as filament wire. The main motive of this research work is to prepare metal matrix composites as functionally graded innovative materials (FGIM), via investment casting as functional prototypes which will have wear resistance properties of SiC and Al2O3 (especially in rapid tooling (RT) applications. The reinforcements in the RT (as functional prototype) have been ensured by SEM analysis. The potential of the analysed materials for the fabrication of novel sensor devices is highlighted. Also the functional prototypes were checked for process capability analysis for batch production.
