Reverse engineering is called laser scanner too. Using 3D scanner (printer) collect the raw data of object surface, create the point cloud, reuse the various software of 3D modeling to collected the data to make fitting. Then elicit the real object of 3D model. Reverse engineering mains to aim at the various complex cured surface. It’s hard to measure the components with the traditional measuring method. Reverse engineering is take the fashion of read with non-contact, no damage to the work piece, used in small automobile parts widely, medical apparatus and instruments, toys, mobile phones, electronic gadgets, mold making, etc. 

Advantages:
1. processing the components unacted on the degree of complexity，can make any complex components
2. reverse engineering mains to aim at the various complex cured surface
3.Do not damage to the work piece.
