Survey paper on different techniques additive manufacturing

Mechanical Engineering

Scientists and engineers impress us daily with revolutionary technologies that turned what was recently considered as science fiction or inconceivable futuristic into reality, making their lives much easier and more interesting. For example have you ever imagined being able to make your own designed glasses frame, kid’s toys, or any other prototypes at your home using raw materials and a single machine? The 3D printing technology enables you to do this and it has much more complicated applications in science and industry. This is survey paper in which the introduced to the 3D printing technology, its definition, history, basic components, and operation theory. The applications of commercialized metal 3-D printers are limited to only rapid prototyping and expensive finished products. This severely restricts the access of the technology for small and medium enterprises, the developing world and for use in laboratories.
