UV-curing three-dimensional printing technology is similar to ink-jet printing

which is one of the Rapid Prototyping Manufacturing technologys integrating droplet ejection technology with layered manufacturing technology and using photosensitive resins as the printing materials. It has the advantages in many aspects such as molding precision

processing velocity

molding temperature

equipment operation

equipment maintenance and running cost. Consequently

UV-curing three-dimensional printing has better developing potentialities and expansive applying foreground. This paper briefly reviewed the working principle and development status of the UV-curing three-dimensional printing and evaluated the advantages of this technology. Special interests were focused on the characteristics of UV-curing three-dimensional printing materials and its research progress. Finally

we prospected the printing materials research trends in the future.
