The Evolution and Impact of Selective Laser Sintering (SLS) 3D Printing Powder
Selective Laser Sintering (SLS) is a powder-based 3D printing technology that uses a laser to fuse material layers into a final part1. This technology has revolutionized the production of complex structures, offering a cost-effective and efficient method for creating intricate designs.Get more news about

The process begins with a thin layer of powder spread across the build platform. A laser then traces the cross-section of the object onto the powder, causing it to sinter, or fuse together. The platform then descends, another layer of powder is spread, and the process repeats until the object is complete.
One of the key advantages of SLS is its ability to print with a variety of materials. These include plastic, metal, glass, ceramic, or composite powders2. This versatility allows for the creation of parts that can be used within industries ranging from healthcare to the aerospace sector.
Among the various materials used in SLS printing, Polyamide 12 (PA12), a type of nylon, has emerged as a popular choice34. PA12 is a long-chain semi-crystalline thermoplastic material exhibiting excellent material properties. It absorbs little water, is resistant to polar and nonpolar solvents, has a low tendency to creep and high impact strength, and can be used over a wide temperature range.
The use of PA12 in 3D printing is not new. White polyamide 12 powder, also known as nylon, is the most tested material for additive manufacturing on the market. Parts made from nylon are robust, stable for long periods of time, chemically resistant, and extremely versatile3.
SLS printing is also much faster with quicker turnaround times than traditional injection molding manufacturing. This cost-efficient general-purpose material is suitable for a variety of applications, including functional prototypes and qualified series production parts from the industry.
In conclusion, Selective Laser Sintering (SLS) 3D Printing Powder has significantly impacted the world of additive manufacturing. Its versatility and robustness have made it an ideal choice for various industries. As technology continues to evolve and improve, we can expect to see even more innovative uses for this remarkable material.
