the manufacturer wants to enhance the life time of laser pointer

The use and charge description and requirement of the battery of laser pointer will be introduced.
In response to market needs, enhance the competitiveness of enterprises, and the short cycle of the mold design, multi-species, low-cost, high-precision provides a shortcut to [1]. Rapid Prototyping (Laser Rapid Prototyping Technology) is the 3D data model within the computer slicing layers of cross-section profile data, the computer whereby information control laser (or nozzle) to selectively sintering the layer then a layer powder material, forming a series with a small thickness of the sheet entities, and then fusion bonded aggregate, bonding, and other means so that the layers were deposited into one, will be able to create a prototype of the new product design, model or mold [ 2]. Therefore, the manufacturer wants to enhance the life time of laser pointer .
Forming principle of the forming principle of the Rapid Prototyping and prototype requirements of 2.1 Laser Rapid Prototyping technology [3] laser rapid prototyping technology forming principle: Rapid Prototyping is the integration of high-tech through the computer, CNC, laser and materials developed. The basic idea is a discrete accumulation of ideas, under computer control and management, according to the part CAD model, the use of the material accurate accumulation (accumulation of points into the surface by the surface accumulation into the three-dimensional entities) to manufacture prototypes or parts, is a new manufacturing methods based on discrete  deposition modeling principles, basic principles and molding process shown in Figure 1. Actually, they don’t understand what does the 3000 hour life time of laser pointer exactly mean.
Figure 1 the basic principles of rapid prototyping CAD software to design a first computer three-dimensional surface or solid model, and then according to process requirements, according to a certain thickness of stratification, the original three-dimensional model into a two-dimensional information (cross-section type like) and then layered, two-dimensional information to generate NC code, by plane processing sequential and continuous process of each thin-layer model and automatically through polymerization or chemical reaction bonding and forming until piled into three-dimensional parts. 2.2 Laser rapid prototyping technology prototype requirements of the Rapid Prototyping is the use of the RP prototype (whether the SL method, the law of the LOM, FDM, SL S-method which a molding method of production). The highly integrated devices play an important aspect of the potential of laser rapid prototyping technology is developed, the use of high accuracy, reliability, high efficiency and low cost of manufacturing equipment.
