Basic Principles Of Rapid Prototyping

Different from traditional mechanical cutting, such as turning and milling, the material reduction method is. “Rapid molding manufacturing technology” is a method of “material superposition” by adding materials by layer-by-layer fusion to generate parts.

The rapid prototyping technology adopts the principle of discrete/stacking molding. According to the three-dimensional CAD model, for different process requirements, layering is performed according to a certain thickness, and the three-dimensional digital model is changed into a two-dimensional planar model with a very thin thickness. Then the data is processed to a certain extent, the processing parameters are added, and each thin layer is continuously processed in a planar processing manner under the control of the numerical control system, and bonded and formed.

In fact, it is based on the principle of “growth” or “add” materials, and the layers are discretely superimposed, and the parts are completed from the bottom to the top. There are many different processes for rapid prototyping, but all rapid prototyping processes produce parts layer by layer, except that the materials used in each method are different and the method of making each layer is different.
