Beautiful Life

Since the first laser in 1960, laser technology research and its application in various fields has been rapid development. Compared with the traditional processing methods, laser processing technology has high coherence, high directivity and high brightness has been widely used in industrial, military, scientific research and daily life, especially in the past 20 years, burning laser pointer manufacturing technology has infiltrated many high-tech Technology and industry, the most prominent of which is developed over the last decade developed countries set precision machinery, computers, numerical control, laser, new materials in one of the new manufacturing technology - rapid prototyping technology (also known as 3D printing technology) , The application of this technology development equipment - rapid manufacturing system, in recent years with more than 40% of the high growth rate.

Laser Rapid Manufacturing Technology (LRMT), also known as laser rapid prototyping technology or laser 3D printing technology, is a computer-aided design, or with the physical reverse method to obtain the prototype or part of the geometric shape, structure and material combination information, Then, the information is transferred to computer-controlled 500mw laser pointer rapid prototyping manufacturing system with light, machine and electricity. By using the laser as a tool, the material can be realized by point-by-point, face-to-face Dimensional pile-up ", and then through the necessary treatment, so that the appearance, strength and performance to meet the design requirements, to quickly and accurately manufacture the prototype or the actual parts and components, without the traditional mechanical processing machine tools and molds technology.

In the broad sense, rapid prototyping belongs to additive forming; in the narrow sense, rapid prototyping should belong to discrete / accumulation forming, that is, according to the three-dimensional design model of the components, the slicing is done by rapid prototyping machine , The two-dimensional profile of the cross-section of each layer is obtained, and the entities to be formed are sequentially superimposed according to these contours.

The whole process of high power laser pointer rapid manufacturing can be summed up in the following three steps: Preprocessing It includes the construction of 3D model, the approximate processing of 3D model, the selection of model forming direction, the slicing of 3D model, polishing and surface strengthening. Under the control of the computer, the corresponding forming head (laser head or nozzle) according to their profile information to do the scanning movement, the workstations layer by layer of the accumulation of material, and then will be a layer of free forming. The layers are bonded and the prototype product is finally obtained.

The molded article is taken out from the forming system and subjected to peeling, post-curing, repairing, grinding, polishing, coating, or final sintering in a high temperature furnace to further enhance its strength. At present, rapid laser manufacturing technology research, according to the different objects and functions can be divided into two categories, namely, rapid prototyping and metal parts rapid and direct manufacturing technology.

Laser rapid manufacturing technology in recent years, one of the fastest growing industrial areas. Relative to the traditional manufacturing process, in accordance with the complexity of the parts and methods used in different, often require weeks or even months of processing time. Based on the computer geometry, structure and connection status of the description, rapid manufacturing of 2000mw laser pointer manufacturing time from a few hours to dozens of hours to complete. It is foreseeable that laser rapid manufacturing technology will have an important impact on the production, processing and manufacturing of materials today.

In recent years, the rapid manufacturing technology based on laser technology (LRPT) is in rapid development, showing three characteristics: First, the rapid emergence of new laser manufacturing process; Second, supporting hardware and software continue to improve; Broaden. Recent developments in LPRT technology include stereolithography (SLA), Selective Laser Sintering (SLS), Laser Laminate Manufacturing (LOM), Laser Cladding (LCF), Laser Near Forming (LENS) , Direct optical manufacturing (DLF), metal laser sintering (DMLS), and shape deposition fabrication (SDM). The following brief overview of several major brightest laser pointer rapid prototyping technology overview.
