快速成形制造技术是由CAD模型直接驱动的快速制造复杂形状三维实体的技术。它能自动、快速、准确地将设计思想物化为具有一定功能原型或直接制造出零件(包括模具)的技术,是制造技术的一次新的变革。当前,快速成形制造技术核心是基于数字化的新型的成形技术,因此,它在要求周期短、效率高、精度高的模具制造中应用较为广泛,对传统模具的加工具有很好的促进作用。 Rapid prototyping technology is a technology that is directly driven by a CAD model to rapidly manufacture complex shaped three-dimensional entities. It automatically, quickly and accurately materialized into the design idea has a certain function prototype or directly produce parts (including mold) technology, manufacturing technology is a new change. At present, the core of rapid prototyping manufacturing technology is based on the new digital forming technology. Therefore, it is widely used in the manufacture of molds requiring short cycle, high efficiency and high precision, and has a good promotion on the processing of traditional molds.
