    Creativity and innovation in any organization are vital to its successful performance. Innovate a product have to consists of many different process of design. The flow of design such as identifying the problem of the product, determining the objective of the research, identifying the customer needs, undergoing survey and analysis data to get the list of metrics. Besides that, house of quality and concept generation will help the research to get know whether the design is full fill the customer needs or not. Concept testing will help to identify the final concept selection. Modelling of the final concept can help to show the target marketing to give their own response on this research. Customer needs can help to make the product undergo further improvement.

    Currently, the world of material requires intensive research to discover a new-class of materials those posses the properties like lower in weight, greater in strength and better in mechanical properties. This led to the study of light and strong alloys or composites. This study focuses to produce current novel aluminium composite with an appreciable density, good machinable characteristics, less corrosive, high strength, light weight and low manufacturing cost product. In this research, an aluminium metal matrix composites (AMMC) (Al-0.5Si-0.5Mg-2.5Cu-15SiC) was developed using the metallurgical powdered method and subjected to the investigation of erosion wear characteristics. Here the solid particle erosion test was conducted on AMMC samples. The article presents, the design of Taguchi experiments and statistical techniques of erosion wear characteristics and the behaviors of the composite. The rate of erosion wear found to decrease with increasing impact angle, regardless of the rate of impact. With higher impact velocity erosion rate increases but decreases with stand of distance.

    The demand for coronary artery stents keeps rising every year with a higher quality, lower cost, faster and economical process. Due to its availability relatively low-cost price and adaptability, Polylactic-acid (PLA) has been identified as an ideal material for biodegradable stents. Previously, laser micromachining was widely used for processing coronary stent but this manufacturing process required high investment. Apart from that, this process was unpractical and unfeasible to be machined with certain material and complex design. Alternatively, FDM 3D printing emerges as a system for producing stent and gained attention for its low cost, high reliability, simple operation, flexibility and has shown potential as promising solutions in stents fabrication. Stent length is one of the key aspects in stents manufacturing. In this work, optical microscope is used to measure the stent characterizations while processing parameter optimization was performed by using Response Surface Methodology (RSM). Printing orientation affects the stent length dimensional accuracy. Both XY and ZX are capable to develop PLA stents but XY-orientation is the ideal printing orientation as it provides good dimensional precision for stent characterizations and a lower risk for the structure and geometry to be sagging.
