What are the characteristics of rapid prototyping technology compared with traditional technology?

Compared with the traditional product processing technology, which requires cutting, casting, forging and welding, the rapid prototyping technology adopted by Shanghai Rapid Prototyping Factory can adapt to the manufacturing and processing difficulties of various materials in our lives, and can obtain materials and parts with excellent performance.

As mentioned above, the rapid prototyping technology of materials is related to the materials, molding methods and structural forms of parts. The essence of rapid prototyping mainly includes the chemical composition and physical properties (melting point, thermal expansion coefficient, thermal conductivity, viscosity and fluidity) of molding materials, which has a great relationship with the use state of molding materials (such as powder, silk or foil). Only by clearly understanding the characteristics of these materials, can we choose suitable materials for our products to carry out rapid prototyping technology, and can we ensure that there is no big gap between our products and those on the market.

The rapid prototyping technology of materials mainly includes the compactness and porosity of molding materials. Whether the microstructure performance of molding materials, the precision and roughness of the surfaces of molding materials and parts, and the shrinkage rate of molding materials (internal stress, deformation and cracking) can meet the specific requirements of various rapid prototyping methods in the production process. The precision of the product will directly affect the structure of the product, the roughness of the product surface will affect whether there are some defects on the product surface, and the shrinkage of the material will affect the precision requirements of the product in the production process. The structure of molding materials will affect the formability of materials to some extent, such as the symmetry of CAD slices and the convexity in Z direction.
