this kind of battery of laser pointer is 1400mAh

The rated capacity of this kind of battery of laser pointer is 1400mAh.
The process is the use of ultraviolet laser beam layer by layer scanning method of light curing adhesive to form a three-dimensional solid workpiece. In 1986, 3D Systems, Inc. introduced a commercialization prototype SLAs-1. SLA process of the highest precision can reach 0.05mm. The ② thin-layer laminated manufacturing (Laminated Object Manufacturing, referred to as LOM) technology thin-film materials such as paper, plastic film, developed in 1986 by the American company Helisys success. By repeated CO2 laser cutting and material paste, layered manufacturing entity workpiece. The LOM process is suitable for the manufacture of large parts, its accuracy of 0.1mm. ③ Selective Laser Sintering (Selective Laser Sintering or SLS) process is the use of powder-like material forming. 1400mAh is the working current of the battery of laser pointer to some extent.
Successfully developed in 1989 by the American University of Texas at Austin, scan high-intensity CO2 laser layer sintering materials, powders and the formation of three-dimensional workpiece, the biggest advantages of the SLS process is more extensive selection. Of the three laser rapid prototyping technology at home and abroad have been more widely used due to the development of a long time, the technology is relatively mature. Three-dimensional workpiece formed by the above method can not be directly used as a mold, the need for subsequent processing, so called laser indirectly into the molding. The main approach: rapid prototyping of the workpiece handling used as a mold. LOM production of paper mold surface treatment instead of sand casting wood mold. The capacity of laser pointer can determine the life time of the battery. A mold parts during the welding repair to return to the tool shop for final machining, then loaded back to the mold up. Generally only damaged parts need to be removed from the mold repair, mold can still remain in the injection molding machine. Tech Group manufactured by Rofin-Sinar StarWeld welding machine is a laser deposition welding using filamentous filler material. It uses a Class I laser shell pulsed Nd: YAG welding laser with electric xyz table and stereomicroscope. Defects of the mold filling material to fill the laser beam and filamentous. The wire is automatically imported, so that the laser beam so that the wire and workpiece surface melt at the same time. Of course, the key lock of laser pointer can keep the children from using the laser pointer.
The total height of the sediment needed to achieve through the multi-layer welding methods.
