Forming deformed material at room temperature under difficult or high-hardening exponent of metals, and can produce a self-cooling hardening effect, the deformation zone the material microstructure and properties can be improved. The German the scholars M.Geiger and F.Vollertsen laser forming compound with other processing methods and processing undertaken extensive research, the technology has been used in automobile cover flexible school calm and other shaped pieces forming. 3 Laser rapid prototyping technology direction of the study 3.1 Material material rapid prototyping technology is the core, any type of rapid prototyping machine for a specific species or specific forms of material and research developed, liquid photosensitive resin SLAs paper using the LOM filamentous material FDM, powder-like materials of SLS. The red ray green laser pointer has drawn a lot of attention.The superiorities of green laser pointer are as follows
The system can be sintered wax, polycarbonate, nylon, metal and other materials. The steel and copper alloy injection mold manufacturing, injection molding 50000 workpiece. From the initial prototype manufacturing in recent years, based on RPM technology mold manufacturing technology, the development of rapid tools and molds become the focus of the application of research and development at home and abroad. RPM-based mold manufacturing methods can be divided into direct molding method and indirect molding method. Direct molding method is a direct RPM technology to produce molds, the method of the RPM technology to direct production of metal molds is the SLS method. Steel and copper alloy injection mold produced in this way, the life expectancy of up to 50000. The blue violet ray green laser pointer will be mainly discussed during the meeting.
However, this method during the sintering process the material the larger contraction, the accuracy is difficult to control. Indirect molding method can be divided into: 1) soft easy-to-mold production. The silicone rubber, metal powder epoxy powder and low melting point alloy prototype will be accurately reproduced into a mold, or prototype surface treatment, metal spraying or physical vapor deposition method, coated with a layer of low melting point alloy to produce the mold .
