With the development of rapid prototyping and rapid tooling, RP and RT technology can be used to inspect rationality of the product design, which can shorten product design period and reduce the product cost.

• 随着快速成型(Rapid Prototyping，简称RP)技术、快速模具(Rapid Tooling，简称RT)技术的发展，可以采用RP技术和RT技术检验产品设计是否可行。 这样缩短了产品设计周期，降低了产品成本。
