Direct digital manufacturing, sometimes called rapid, direct, instant, or on-demand manufacturing, is a manufacturing process which creates physical parts directly from 3D CAD files or data using computer-controlled additive and subtractive fabrication and machining techniques with minimal human intervention. When a small, low-cost device is used, it is also called desktop or personal manufacturing. ,Digital Manufacturing consists of new business processes, design methodologies, organizational approaches and software tools that help manufacturers improve their competitiveness and product profitability by planning, designing and implementing better manufacturing processes. Digital Manufacturing concepts have been developed to address increasing demands on manufacturing to meet corporate objectives. Demand for higher quality products and more rapid introduction and ramp-up of new product innovations has been an executive- level mandate for many manufacturers. At the same time, continued market pressures have dictated that companies must continue to improve efficiency, drive out cost and increase throughput of facilities. Additionally, manufacturers are now working in a much more disperse, complex supply
