Application analysis of laser rapid prototyping in various industries

Rapid prototyping (RP) technology is a new prototype manufacturing technology developed in the mid-1980s. In the early stage of product development, the required CAD drawings or STL files are designed, and the model is made as a design before actual production. The original model of validation, product modification, functional testing, and mold development is the prototype. RP technology integrates mechanical engineering, CAD, numerical control technology, laser technology and material science technology, and can automatically, directly, quickly and accurately transform design ideas into prototypes with certain functions or directly manufactured parts, so as to quickly evaluate product design , Modification and functional testing, adults shorten the product development cycle: it has the advantages of agility, suitable for any shape, high flexibility or rigidity, and high integration. It is widely used in machinery, automobiles, electronics, communications, aerospace and other fields. Since the development of RP technology, more related equipment has been developed to meet the needs of various models. Features of e-manufacturing based on laser sintering technology. German EOS company has been committed to the research and development of laser sintering rapid prototyping system and equipment manufacturing since 1989. The laser sintering technology possessed is exactly the core technology of e-manufacturing advocated by EOS company. . e-manufacturing refers to fast, flexible, and low-cost manufacturing directly from digital files. This manufacturing method can currently meet the different needs from single-piece product manufacturing to mass production of individualized products, enabling a new combination of product design and manufacturing. Its main advantages are simply referred to as: any shape, any time, anywhere . The specific instructions are as follows: 　　 (1) Any shape, that is, any shape can be manufactured through design. The e-manufacturing based on laser sintering technology allows designers to no longer be restricted by traditional manufacturing technology to modify their designs, and modeling designers or industrial designers can realize their endless creativity. For example, the special-shaped waterway design has become a revolutionary design to improve the heat dissipation efficiency of the mold to reduce the cooling cycle.　　(2) Any time, it is applicable to any stage in the product life cycle. e-manufacturing is applicable to any stage in the product life cycle from the pre-development period to the supply of components after the product is on the market, and is not restricted by the replacement of professionals and working time. It is obtained through CAD or various design software 3D data can be directly and quickly produced prototype samples or solid parts.　　(3) Any place is applicable to any industry. The e-manufacturing concept has a competitive advantage. It can easily produce molds or parts with complex structures and high prices. It is applicable to high-tech or civilian industrial fields such as design, construction, aerospace, automobiles, and robots. At present, the direct metal laser sintering (DMLS) technology presents e-manufacturing advantages, which can directly sinter copper alloy powder, aluminum silicon magnesium powder, stainless steel powder, mold steel powder, and titanium alloy powder, making mold development from rapid tooling. Progress to the production of high-end molds with special-shaped waterway structures or complex geometric shapes. (The above is edited and compiled by the metal laser cutting machine on the Internet.
