Compared with traditional molding, rapid prototyping, as its name implies, is a relatively fast way of production. When producing parts or items in relatively small numbers, rapid prototyping is a more efficient and economical choice. It is a breakthrough since rapid prototyping reduces the troublesome processes of traditional method. Rapid prototyping can also produce complicated prototypes without any troubles. Fast, efficient, and convenient, rapid prototyping is indeed the best choice for producing models.
