Problems solved by technology

[0005] At present, light-curing rapid prototyping technology is a comprehensive and cross-cutting cutting-edge technology, and there are many shortcomings in practical applications. It is specially formulated according to the needs, which affects the effect of light-curing rapid prototyping and product quality; for example: the combination of diamond and resin used in ultra-thin grinding wheel cutting saw blades is not ideal, and the combination of diamond and light-curing resin is not good, resulting in insufficient strength. ; For example: in light-curing rapid prototyping, some light-curing molding processes are not rigorous enough, the curing speed is slow, the ratio of the reinforcing agent is not reasonable enough, the energy of the focused beam is insufficient, and the scanning curing track is not accurate enough, resulting in the internal organization and compactness of the product parts. Poor performance, material ratio and processing technology are not ideal
