In recent years, with the continuous improvement of the industrial chain of China's precision casting parts industry and the continuous improvement of the technical level, the downstream demand field has shown an increasing demand for precision casting parts. However, traditional precision casting production processes still have many problems, which plague a large number of precision casting manufacturers. In this market background, Tiangong Casting uses its high-performance light-curing 3D printing equipment with its high-performance photocuring 3D printing equipment, and has launched a new Quick Casting application with integrated system. The solution can effectively solve the pain point problem in the traditional precision casting process, and at the same time guarantee the production of high quality castings.

Fast precision casting technology is the perfect combination of light curing rapid prototyping technology and traditional investment casting technology. Light-curing rapid prototyping technology integrates seamlessly into the investment casting process.

The traditional investment precision casting is a near-net forming process. The casting has high dimensional accuracy, complex structure and strong material adaptability. It is widely used in the aerospace field with high added value and weight loss. The process is through the steps of making metal molds, making wax molds, grouping trees, hanging sandblasting shells, steam dewaxing, shell baking, casting, post-casting processing and casting inspection. The traditional precision casting technology has a long manufacturing cycle and a high cost, and cannot respond to market demands quickly.

The rapid solidification technology (SLA) involved in rapid precision casting technology is an advanced manufacturing technology with high flexibility. The CAD model of the part can directly drive the equipment to complete the prototype manufacturing of the part and apply it to the direct manufacturing precision casting model. It can greatly improve the flexibility of investment casting and achieve rapid casting. Compared with other rapid prototyping methods for investment casting (such as SLS, FDM, etc.), it has great advantages in dimensional accuracy and surface quality
