The material accumulation manufacturing process is to gradually accumulate and grow parts in the form of micro-element superposition. In the manufacturing process, the three-dimensional solid model data of the part is processed by the computer to control the accumulation process of the material to form the desired part. The advantage of this type of process is that parts of any complex shape can be formed without the need for production preparation activities such as tools and fixtures.
Manufactured prototypes are available for design evaluation, bids or prototype presentations. Therefore, this process is also called rapid prototyping technology. Rapid prototyping technology is used in the manufacture of product samples, mold manufacturing and a small number of parts. It has become an effective technology to accelerate the development of new products and realize concurrent engineering, so that the products of enterprises can quickly respond to the market and improve the competitiveness of enterprises.
