Industrial equipment models and other mechanical models to display, especially some relatively large machinery, will generally use models to display. Industrial model, commonly known as hand plate, hand plate model and rapid prototyping, the main production methods are CNC processing, laser rapid prototyping and small batch production of silicone mold, widely used in industrial new product design and development stage. In a relatively short time to process and design consistent physical model, designers for product appearance confirmation and functional testing, so as to improve the design scheme. To achieve the purpose of reducing the development cost, shortening the development cycle, and quickly obtaining customer recognition.
