Rapid Prototyping is aggressively transforming manufacturing industries, posing an intensive threat to conventional approaches. Despite a costly investment, manufacturers continue to adopt rapid prototyping as a means to evaluate the product design effectively. The significance of 3D printing in rapid prototyping is quite notable, mainly because of its flexibility against bulky CNC machines and rapid reach to mass community, making 3D printing a household name. A market report from IDTechEx predicts the global 3D printing market to grow at least $7 billion by 2025. The future of 3D printing, however, relies heavily on the ability to produce metal and composite parts, rather than dummy plastics that can be hardly find a practical use.
