1.1 PREAMBLE A large number of technologies have emerged in the past few years in response of the pressing need for reducing prototyping and product development lead-time. During the last two decades there has been a continued acceleration in product and market variation. The success of electronics, telecommunications, automotive, medical, packaging, appliances, leisure and sports industries in responding to rapidly varying customer demands for higher quality standards with lower costs depends on the ability to develop the product with the application of state-of-art technology. The demand for shorter development time, time to market and reduced product life cycle resulted for the emergence of new paradigm called Rapid Prototyping Rapid…show more content…
Also, an allowance, called draft allowance is provided on the vertical surfaces if the pattern to facilitates removal from the die. Making a pattern using wax or some other material that can be melted away makes the mould. Pattern may be made in loose pieces and then welded together by means of the hot wire resistance welding iron to form the complete pattern. The numbers of patterns are welded together along with the common gating system. 1.2 CLASSIFICATION OF RAPID PROTOTYPING TECHNOLOGY. Technological advancement and globalisation resulted in increased competition. This has enhanced new methodologies and quality awareness along with the reduction in manufacturing time and lead-time in new product development. The most promising technology is the rapid manufacturing, the combination of Rapid Prototyping (RP) and Rapid Tooling (RT) technologies. Figure 1.1 Classifications of Rapid Prototyping methods (adopted from 1998Pham and…show more content…
• To decrease development time. • To decrease costly mistakes. • To minimize sustaining engineering changes. • To extend product lifetime by adding necessary features and eliminating redundant features early in the design. Application of Rapid manufacturing in new product design and development reduces the lead-time to considerable extent and also reduces the cost of tooling which in turn results in overall cost reduction. A Rapid Prototyping and Rapid Tooling promise to reduce the tooling lead time by 50% or more. These types of technologies are new and much used in Indian scenario is worth As an engineer, they must be well known and with this the study of this process in details was taken up as a Dissertation on “Rapid Prototyping: Tool for Casting” 1.4 OBJECTIVES OF THE WORK: 1. To study the feasibility of Rapid Prototyping (ABS material) in prototype building to reduce lead time. 2. Cost optimisation of RP die using Rapid Prototyping FDM process. In this dissertation work, the feasibility of RP ABS was studied for producing prototype for initial. The techno-economic analysis for the above process was also carried out. 1.5 METHODOLOGY OF
