the cutting of transparent materials is difficult

Therefore, the cutting of transparent materials  is difficult, even impossible. UV transparent

material have a better absorption rate, so the idea of an application of UV laser in the field of micro-injection technology. Laser rapid prototyping technology is widespread international concern

in recent years, an advanced solid free forming technology to directly forming a high-performance dense metal parts, with no mold, short cycle, low-cost, fast response in the market. For this

type, based on the original green laser pointer , some features have been improved.green laser pointer is easy to manage
This paper analyzes the laser rapid forming of residual stress formation mechanism and distribution characteristics, an overview of the impact of residual stress on the forming pieces of

mechanical properties, structural dimensions, the actual use of, and discusses the experimental determination of residual stress and adjustment and to eliminate residual effective means of stress.

Laser rapid prototyping technology is based on laser cladding stacked manufacturing technology, it rapid prototyping (RP) free forming of the advantages of laser cladding technology, to achieve

the performance of complex structures, dense metal parts directly forming with high flexibility, short cycle, low cost, fast response in the market. The customer can use green laser pointer for a

really long time without any troublesome problems.
Is an organic blend of materials technology and manufacturing techniques, "the design of new materials, new materials preparation and high-performance complex near net shape parts rapid

prototyping integration of new technologies. Laser rapid prototyping to high-energy laser beam as a moving heat source, on the one hand, the laser rapid heating and cooling the extreme non-

equilibrium conditions can not be achieved by conventional means to provide for material processing, forming parts with fine, dense tissue, and excellent overall performance; but another the one

hand, the local heat input caused by the uneven temperature field would inevitably lead to local thermal effects, reflected in the weld pool during solidification and subsequent cooling process is

inconsistent, thus forming in the formation of residual stress and deformation. Residual stress as a internal stress. For example, someone wants to create some romantic atmosphere in some special

meaningful occasion, this kind of green laser pointer can be used to achieve this special effect.
