The technical principle of rapid prototyping

Rapid prototyping technology is a new technology that integrates advanced technologies such as computer-aided design (CAD), computer-aided manufacturing (CAM), computer numerical control (CNC), precision servo drive, laser and material science. Its basic idea is:


Any three-dimensional part can be regarded as the superposition of many two-dimensional plane contours of equal thickness along a certain coordinate direction.


Therefore, according to the three-dimensional design model of the product formed on the computer, the three-dimensional model in the CAD system can be divided into a series of plane geometric information, that is, sliced into layers to obtain the contours of the cross-sections of each layer. Or hot-melt materials, etc., to form each cross-sectional profile and gradually superimpose it into a three-dimensional product.
