Green laser will attract more and more customers in the near future

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     green 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).    green laser will attract more and more customers in the near future.
As a kind of mold to replace the traditional wood, plaster, steel, cement, paraffin, production of prototypes (like mold), to create a work / mold (whether by casting forming method is not a spray forming method, electrochemical forming, etc.) therefore, for rapid mold design and manufacturing, RP prototype design and manufacturing is an important part, because its shape, size, surface finish, will directly affect the future of rapid tooling manufacturing quality. Therefore, the proposed RP prototype of this, the following requirements: (1) to facilitate stripping, determined parting direction, the RP prototype surface should Demoulding prohibit the emergence of the inverse slope. Thus the RP prototype three-dimensional solid modeling, the need of the surface mold release operation, given draft angle based on experience. Of course, most customers pay much attention to the continuous wave output of   200mw laser pointer .
Of course, can also be the prototype manual processing. (2) The prototype should have good strength and stiffness to control the mold deformation. When casting molding, liquid injection continue to impact the prototype, it is required to prevent the prototype collapsed in cast molding, cracking and affect the quality of the mold. (3) prototype should be the correct shape, the exact size and high finish. (4) the prototype of the wall thickness should be uniform, to ensure that the gap between the punch and die. Easily cause uneven wall thickness, the casting mold shrinkage, bubbles, dents and other defects, or even cracking. Laser Rapid Prototyping of basic steps. The establishment of the so-called three-dimensional modeling of three-dimensional data model is a computer can understand.    green laser pointer   has attracted many customers in the domestic and oversea market.
