3D Printing is indeed a unique technology which is benefiting almost all sectors. And since we are operating in a digital world a technology like this can only help change the dynamics of manufacturing with tool making to benefit the end users. The technology is also called Additive manufacturing, Rapid Prototyping and DIGITAL MANUFACTURING. How does this operate? In 3D printing, the first step is to make a virtual design of the desired object, and subsequently the virtual design is made in a CAD file by using a 3D scanner or by using a 3D modeling program with a software. The next step is to get the 3D file to print it; the 3D modeling software in the 3D printer will "slice" the design into numerous layers, and uses the material to create the object layer by layer. It is a process of making 3D objects using plastic, metal, ceramic, wood, gold powder and composite materials, usually layer upon layer, to build physical models, prototypes, patterns, tooling components, and production parts. There is a great deal of R & D going into the various materials to ensure it can be used for various requirements. It is estimated that the global 3D printer market will grow at a CAGR of 68% during the period 2016-2021.
