The current study and development of rapid prototyping

As one of the advanced manufacturing technologies, Rapid Prototyping produces parts based on material additive manufacturing process. RP parts can use different materials in gas, powder, solid layers and liquid. This paper generally deals with the principle, process, and application of RP. During a decade of research and developments, RP have made great progresses. There have been several typical layer creation techniques known as Stereolithography, Fused Deposition Modeling, Three Dimensional Printing, Selected Laser Sintering, Laminated Object Manufacturing and so on .Up to now, RP have attained applications in parts design and manufacturing, die/mould fabrication, medical context and micro-fabrication. RP will take steps to improve precise and efficiency. Lower costs and more applications also will be getting.ndapplicationofRP .Duringadecadeofresearchanddevelopments,RPhavemadegreatpro gresses.Therehavebeenseveraltypicallayercreationtechn
