1, CNC rapid prototyping (metal, plastic):
CNC rapid prototyping manufacturing is a traditional processing, with removing the excess material of the rough pieces to get the required prototype .From a technical point of view, it is a processing method that combines CAD,CAM, CNC and other advanced technology to get the 3D model from digging the block of material in the CNC Center. In the prototype industry, CNC processing general used for some of the larger piece of the shell structure and the solid board, and also can make some structural model for functional testing. It can use various material.
CNC prototype making process:
get drawings →design tool path → Transmit tool path to CNC centers → automation processing → manual after-treatment (polishing, painting, printing, etc.)
2, vacuum casting (silica gel model) prototype:
In a vacuum state, using the original model to produce silicone molds, then casting with the PU materials to clone a exactly same copy of the original model. Because the technology is fast, low-cost, so greatly reduces the costs, cycle and risk of the product development.
3, SLA laser rapid prototyping
Rapid prototyping technology is developed based on the modern CAD / CAM technology, laser technology, CNC technology, precision servo-drive technology and new materials technology .The materials used in forming, shaping principles and system characteristics are also different according to Different types of rapid prototyping systems. However, the basic principles are the same, that is "layered manufacturing, Layer-by-Layer," similar to the integral procedure in math. Figuratively speaking, rapid prototyping is like a "three-dimension printer".
