“…Commercially pure Al was melted in a silicongraphite crucible in an electric furnace. The selection of input process parameters was initially based upon previous reported literature [11,12] should be noted that this may be a constraint from stirring set-up point of view. Hence the range of Al 2 O 3 particles in Al was selected as 5-10%.…”

“…In this process, a polymer sheet is used to seal the open ends of the mould [9,10]. Literature review reveals that a lot of work has been reported on the optimization of FDM, SC and VM processes and their various parameters like pouring temperature, film thickness and jolting time for producing sound casting [11][12][13]. But hitherto no work has been reported on modelling the hardness of biocompatible implants prepared by the replication of FDM-based acrylonitrile butadiene styrene (ABS) patterns and combining with VM and SC processes.…”

In the present work, effort has been made for modelling the microhardness of biomedical implant prepared by combining fused deposition modelling, vacuum moulding and stir casting (SC) process. A dynamic condylar screw (DCS) plate was selected as a real '3D' biomedical implant for this case study. The DCS plate, made of acrylonitrile butadiene styrene material, was fabricated as a master pattern by fused deposition modelling. After preparation of the master pattern, the mould cavity was fabricated by the vacuum moulding process. Finally a metal-matrix composite of Al and Al 2 O 3 prepared by SC process has been poured in the vacuum mould for fabrication of DCS plate. This study outlines the replication procedure of DCS plate in detail from the master pattern to final product. The contribution of the paper is towards finding out the effect and optimum values of three different process parameters (namely: percentage composition of Al and Al 2 O 3 , vacuum pressure and grain size of silica) towards microhardness of the DCS plate manufactured by the combined process.

Investment casting process is known to its capability of producing clear net shape, high-dimensional accuracy and intricate design. Consistent research effort has been made by various researchers with an objective to explore the world of investment casting. Literature review revealed the effect of processing parameters on output parameters of cast specimen. This article highlights the advancements made and proposed at each step of investment casting and its hybridization with other process. Besides, investment casting has always been known to manufacture parts such as weapons, jewellery item, idols and statues of god and goddess since 3000 BC; this article reviews the present applications and trends in combination of rapid prototyping technique as integrated investment casting to serve in medical science. Advancements in shell moulding with incorporation of fibre and polymer, development of alternative feedstock filament to fused deposition modelling are duly discussed. The aim of this review article is to present state of art review of investment casting since 3200 BC. This article is organized as follows: in section ‘Introduction’, introduction to investment casting steps is given along with researches undertaken at each step; in section ‘Rapid prototyping technique’, background is given on the concept of rapid prototyping technique by examining the various approaches taken in the literature for defining rapid prototyping technique; section ‘Biomedical applications of RPT’ presents the medicine or biomedical applications of investment casting and rapid prototyping technique; section ‘Future trends’ provides some perspectives on future research and section ‘Conclusion’ closes the article by offering conclusions.

“…It is indicated a least improvement of mechanical strength compared to the monolithic aluminum composites before T6 heat treatment. Rupinder Singh and Gagandeep Singh [6] concluded improving dry sliding wear properties of aluminum metal matrix composite of Al-6063 matrix and SiC reinforcement particle by vacuum process. Particle size of SiC and vacuum molding process were studied to find out their effect on wear properties of composite.…”

Hybrid metal matrix composites new generation of engineering materials with better mechanical and tribological properties. Al6063 alloy has the matrix material and reinforcement SiC and ZrO2 micro particles are selected for the study. In this work, Al6063/ SiC/ZrO2 hybrid composite fabricated with different wt. % of reinforcements (0.5, 1, and 1.5 wt. % SiC and 1 wt. % ZrO2 constant for all composites) by using stir casting process. The thixoforming process applied to casted composite. The SiC and ZrO2 particle was distributed in the Al-matrix are visible in the SEM micrographs .The hardness value of the composite 34.75% increased due to the addition of constant 1 wt. % of ZrO2 and varying SiC reinforcement particles. The charpy impact strength of Al composite was increased by 23.52 % with the addition of the constant 1 % wt. ZrO2 and 1 wt. % SiC particles. Wear behavior of Al6063/SiC/ZrO2 hybrid composite was tested using pin-on-disc machine. The wear volume loss decreased for 1.5 % wt. SiC and 1 wt. % ZrO2 compared to other composite. The worn surface morphology has revealed that Al6063 base alloy with deep groove. The composite with 0.5%, 1% wt. SiC and constant 1 wt.% ZrO2 showed more debris, dilamation and cleavage particles formed on the pin surface. The composite with 1.5 % wt. SiC and constant 1 wt.% ZrO2 showed less wear loss and smooth surface formation.
