过去 15 年出现的快速原型 (RP) 技术均基于通过计算机辅助设计 (CAD) 通过堆叠二维轮廓直接创建三维几何形状的原理。迄今为止，大多数 RP 零件都用于原型设计或加工目的；然而，未来大部分可能会作为最终用途产品生产。在这种情况下，术语“快速制造”使用 RP 技术作为最终用途产品的生产工艺。本文报告了成本分析的结果，该分析是为了将传统制造路线（注塑成型）与分层制造工艺（立体光刻、熔融沉积建模和激光烧结）在不同数量零件的单位成本方面进行比较。结果表明，对于某些几何形状，使用层制造方法比使用传统方法进行数以千计的生产更经济。
Rapid prototyping (RP) technologies that have emerged over the last 15 years are all based on the principle of creating three-dimensional geometries directly from computer aided design (CAD) by stacking two-dimensional profiles on top of each other. To date most RP parts are used for prototyping or tooling purposes; however, in future the majority may be produced as end-use products. The term 'rapid manufacturing' in this context uses RP technologies as processes for the production of end-use products.This paper reports findings from a cost analysis that was performed to compare a traditional manufacturing route (injection moulding) with layer manufacturing processes (stereolithography, fused deposition modelling and laser sintering) in terms of the unit cost for parts made in various quantities. The results show that, for some geometries, it is more economical to use layer manufacturing methods than it is to use traditional approaches for production in the thousands.
