What Are the Characteristics of Rapid Prototyping Technology Compared with Traditional Technology

Compared with cutting, casting, forging and welding in traditional product processing technology, rapid prototyping technology used by rapid prototyping factory can adapt to the difficulty of manufacturing and processing of various materials in our life, and it can acquire excellent material and parts structural ability.

As mentioned above, the rapid prototyping technology of materials is related to materials, forming methods and structural forms of parts. The essence of rapid prototyping mainly includes the chemical composition, physical properties (melting point, thermal expansion coefficient, thermal conductivity, viscosity and fluidity) of the forming materials, and the use status of the forming materials (such as powder, wire or foil) has a great relationship. Only when we recognize the characteristics of these materials can we choose the appropriate materials for rapid prototyping technology of the products produced. It can ensure that there is no big gap between the products produced and those put into the market.

Rapid prototyping technology of materials mainly includes density and porosity of materials. Check whether the properties of the microstructures of the moulding materials can be satisfied in the production process. The precision of profile materials, parts and surface roughness, shrinkage (internal stress, deformation and cracking) of forming materials are examined to see if they can meet the specific requirements of various rapid prototyping methods. The accuracy of the product will directly affect the structure of the product. The roughness of the product surface will affect whether there are certain defects on the product surface. The shrinkage of materials will affect the accuracy requirements of products in the production process. The structure of the forming material will affect the formability of the material to a certain extent, such as the symmetry of the CAD slice, Z-direction convexity and so on.
