RAPID PROTOTYPE

Rapid Prototyping Technology concept namely the RP (Rapid Prototyping) Technology is put forward of the concept of dating back to 1979, the Japanese production Technology research institute at the university of Tokyo professor he wei male modelling method, invented the laminated model 1980 jade show male light modelling method is introduced, the idea is raised, the pill GuYang. Continue to study in 1984, and in 1987, for trial production.

In 1988, the United States 3 d Systems company pioneered - laser Stereo modelling the SLA rapid prototyping practical device (Stereo Lightgraphy Apparatus), with annual sales growth of 30% ~ 30% growth in the world market.With the improvement of the performance of the scanning galvanometer, and the development of material science and computer technology, rapid prototyping technology has been mature, and in 1994 formally entered the stage of popularization.

Rapid prototyping technology breakthrough in the "blank - machining - finished product" of the traditional pattern of parts processing, started without cutting tools make a part, is a kind of unprecedented processing method of thin layer superposition.Compared with the traditional machining method, rapid prototyping processing has the following advantages:
1, can quickly create a free-form surface and a more complex shape parts, such as parts of the grooves, convex shoulder and hollow parts, etc., greatly reduces the new product development cost and development cycle.
2, non-contact processing, do not need necessary for machine tool cutting tool and fixture, tool wear and cutting force.
3, no vibration, noise and cutting waste.
4, which can realize fully automated production at night.
5, high processing efficiency, can quickly produce products entity model and mould.
