Selective Laser Sintering (SLS) was developed at the University of Texas in Austin, by Carl Deckard and colleagues. The technology was patented in 1989 and was originally sold by DTM Corporation. DTM was acquired by 3D Systems in 2001. The basic concept of SLS is similar to that of SLA. It uses a moving laser beam to trace and selectively sinter powdered polymer and/or metal composite materials into successive cross-sections of a three-dimensional part. As in all rapid prototyping processes, the parts are built upon a platform that adjusts in height equal to the thickness of the layer being built. Additional powder is deposited on top of each solidified layer and sintered. This powder is rolled onto the platform from a bin before building the layer. The powder is maintained at an elevated temperature so that it fuses easily upon exposure to the laser. Unlike SLA, special support structures are not required because the excess powder in each layer acts as a support to the part being built. With the metal composite material, the SLS process solidifies a polymer binder material around steel powder (100 micron diameter) one slice at a time, forming the part. The part is then placed in a furnace, at temperatures in excess of 900 °C, where the polymer binder is burned off and the part is infiltrated with bronze to improve its density. The burn-off and infiltration procedures typically take about one day, after which secondary machining and finishing is performed. Recent improvements in accuracy and resolution, and reduction in stair-stepping, have minimized the need for secondary machining and finishing.
The main material for the SLS are the metal part or Nylon material which are commonly used in the industry or consumer fields. contact us to do the business, we are your best partner from beginning to end to give you the best service.

The biggest difference between LCD splicing screen and traditional LCD TV screen is industrial manufacturing. LCD TVs are aimed at half of the family, while LCD splicing screens are aimed at industrial projects. LCD TV work will continue to play for 48 hours will appear failure, and LCD splicing screen can be played continuously for 365 days. The service life of LCD backlights used in ordinary LCD TVs ranges from 10,000 to 30,000 hours, and the lifetime of the LCD screens used by Diedeo can be up to 100,000 hours. This ensures the use of spliced ​​displays. The consistency of brightness, contrast and chromaticity of each LCD panel after a long period of use, and to ensure that the life of the display screen is not less than 50,000 hours.
LCD splicing screens and LCD TVs are used to display image signals, but the performance and configuration of the two are completely different. First of all, the LCD TV's screen and LCD splicing screen are different. The LCD panel used for LCD splicing is higher than the LCD TV's panel technology. The liquid crystal splicing screen made with the LCD TV screen is obviously different from the screen with high brightness, and the color and the gradation are obviously distorted under the high-brightness screen. In addition, the LCD splicing screen adopts parallel high-speed graphics processing technology, realizes the unified processing of multiple high-speed video signals, fundamentally replaces the card-type splicing controller, and solves the problem that the number of VGA signal inputs is limited. 
LCD splicing screen will integrate the current best high-definition, high-brightness and high-gamut liquid crystal display technology, embedded hardware splicing technology, multi-screen image processing technology, and signal switching technology to form a liquid crystal splicing display system. . The liquid crystal splicing wall is a brand new large-screen splicing method, which can be spliced ​​indefinitely.
After many years of development, liquid crystal display technology has occupied an important position in the liquid crystal display area. The splicing screens are highlighted by their advantages of ultra-lightweight, ultra-thin, low power consumption, no radiation, high definition, long life, and low maintenance cost. The liquid crystal splicing screen uses a liquid crystal display as a basic display unit, a liquid crystal display technology, and a pure hardware high-speed real-time splicing control technology. All input signals can be freely displayed in a display wall window, and a full support for image multi-screen, roaming, and the like. PIP, overlay, zoom and other high-end display functions.
Emperor Aidi believes that its controller is tailor-made for the display and dedicated to the machine to maximize the performance of the display unit. LCD splicing screen images are clear, flexible and diverse, rich in display content, can give users the greatest freedom of design space, provide shocking display. The LCD TV can only display half of the simple picture, although there are some LCD TVs on the market, but the interface and signal types can not be compared with the LCD splicing screen.

On the whole, the large-screen display market is blooming and brilliant. It really makes people dizzying and dazzling. With the networking, intelligence, and socialization of business information. More and more mid- and low-end manufacturers use large-screen display products for brand promotion, differentiated marketing, and gathering or disseminating commercial information. Nowadays, the hottest and hottest LCD splicing screen in the big screen splicing market has become the friend they most need. However, there are many customers who are not traditional security industry professional customers, just know the product name, just stay on such a concept, instinct that the LCD splicing screen are similar.
