Figure 1 shows the process of laser rapid forming, which mainly includes laser cutting, welding, sparking, laser sintering, cladding, and others. Laser cutting is to cut the part into desired shape or line by high-power laser beams moving in relatively small or large areas. Welding is to use laser beams to melt source materials and combine them by filling and connecting melted faces. Sparking is to use laser beam to remove sharp edges and remove burrs from a certain height. Laser sintering is to use laser to heat the material and achieve effects such as forming and surface hardening. Cladding is to use laser to heat and melt the source material which is then sprayed onto the substrate.

Figure 2 is the principle of laser rapid forming. It is mainly to use laser beam to melt the welding material and join it to the base material. After irradiation, the base material and welding material will be joined together according to the designed shape.

Application of Laser Rapid Forming and Precision Casting
The combination application of laser rapid forming and precision casting can shorten the production cycle and reduce production costs. Laser rapid forming is used to form the casting parts with complex shapes and patterns. Precision casting uses raw materials with high thermal conductivity and is with good moldability characteristics, which can make the laser rapid forming process simpler and faster. Compared with traditional casting, the combination application of laser rapid forming and precision casting can greatly improve the accuracy of parts and reduce casting defects.
Conclusion
The combination application of laser rapid forming and precision casting technology is one of the most effective ways to manufacture precision casting parts. This technology can satisfy customer requirements including high precision and mass production, reduce the cost and shorten the production cycle, and significantly improve the efficiency. With the development of laser rapid forming and precision casting technology, it will be widely used in the future.
