OVERVIEW OF RAPID PROTOTYPING TECHNOLOGIES: 3D PRINTING

Abstract

Rapid prototyping is an additive manufacturing. It is a layered manufacturing. It is different from subtractive manufacturing process.  In Rapid Prototype manufacturing, the physical object is obtained directly from geometric 3D CAD model with the help of computer by using Catia or Pro/e or Creo software. It is the latest amazing manufacturing and revolutionized manufacturing industry. It is a new manufacturing process in engineering. Rapid prototyping is a unique in manufacturing. It is a new development in manufacturing. It is different from conventional and unconventional machining process. Rapid prototyping is a fast emerging technology in product development. Rapid prototyping is a useful tool. It produces the products at faster rate and at lower cost than conventional manufacturing systems.  One of the most exciting innovations is 3D –Printing. It is recently emerged in mechanical engineering at MIT, USA.  3-D printing offers the realistic possibility that anyone, anywhere in the world can produce any object they need on demand. 3D Printing machines have shorter manufacturing time, lower costs and better surface quality of part. The 3D-Printing Technology is fast developing one with tremendous market potential.  In this paper over view of composites, 3D-Printing, advantages, disadvantages and its future scope will be discussed.
