【Abstract】 A new non communication optical fibertapered optical fiber is applied in the desktop rapid prototyping system (DRPS), which delivers higher output energy than non tapered optical fibers of the same output diameter,and greater transmission ratio. The stereolithography process and its principle are discussed. The optical subsystem is introduced firstly,then the choice and design of UV source,and the design,transmission,coupling,focusing of tapered optical fiber. The optical subsystem has the following advantages: low cost,small size and high efficiency. Application of the optical subsystem in DRPS will provide a concrete foundation for wide uses of the system.更多还原
