What is the connection and difference between free forging and laser additive manufacturing technology?
Both free forging and Laser Additive Manufacturing (LAM) belong to the field of advanced manufacturing technology, and they are related in some ways, but also have some differences. Connection: Both are additive manufacturing technologies: Both free forging and laser additive manufacturing create parts by adding materials layer by layer, which is more efficient and flexible than traditional reduced-material manufacturing (such as cutting). Achieve complex structure: Both enable the manufacture of parts with complex shapes and internal Spaces, with greater design freedom. Difference: The working principle is different: free forgings achieve plastic deformation of shape through heat treatment and forging processing, while laser additive manufacturing uses a laser beam to melt and solidify metal powder or wire layer by layer to achieve part manufacturing. Different applicable materials: free forging is mainly suitable for metal materials, such as titanium alloy, nickel-based alloy, etc. Laser additive manufacturing can be applied to a variety of materials, including metals, plastics, ceramics, etc. Different precision: Laser additive manufacturing can achieve high precision and surface quality, suitable for the manufacture of fine structures; Although free forging can also achieve certain accuracy requirements, it is relatively low. The degree of technology maturity is different: laser additive manufacturing is relatively new, and the technology is still developing; As a traditional metal processing technology, free forging technology has been relatively mature and widely used. In general, free forging and laser additive manufacturing are advanced manufacturing technologies, each with its own advantages and scope of application. When choosing which technology to use, it is necessary to consider factors such as specific application requirements, material characteristics and shape complexity.
