Impressive advances in 3D printing technology and free-form fabrication have made rapid prototyping a very attractive option when using the investment casting process. This economical, time-saving alternative to traditional prototype creation can get parts in production and to market significantly faster and less expensively. The process produces a 3D model by printing or depositing numerous layers of prototyping material, creating the specified geometry. In just days, a prototype can be ready to evaluate.
