SLS is an additive manufacturing (AM) technology that includes utilizing a high-power laser to sinter small particles of polymer powder into a solid structure based on a 3D model. Among engineers and manufacturers, SLS 3D printing is a preferred choice. Due to its numerous advantages, this technique is suited for speedy prototyping in small-batch, bridge, or custom manufacturing. SLS printing has become more affordable for a broader range of businesses. More player technologies that were previously only available to a few high-tech businesses are now available as a result of recent developments.
SLS 3D Printing can be done in a variety of ways.
The powder is dispersed in a thin layer on top of a platform inside the build chamber. The printer heats the powder to slightly below the melting point of the raw material, allowing the laser to boost the temperature of particular areas of the powder bed while tracing the model to solidify a part.
A cross-section of the 3D model is scanned with a laser, which heats the powder to just below or slightly above the melting point of the material. The particles are mechanically fused together to form a single solid component. The unfused powder supports the item during printing, eliminating the need for special support structures. The platform is then lowered into the build chamber one layer at a time, typically between 50 and 200 microns, and the process is repeated until the pieces are complete.
Cooling: The build chamber must be somewhat cooled inside the print enclosure and then outside the printer after printing to ensure ideal mechanical characteristics and avoid warping in parts.
After the pieces have been built, they must be removed from the build chamber, separated, and cleaned of excess powder. The powder can be recycled, and the printed goods can be handled further by media blasting or tumble.
3D printing materials used in SLS
Nylon is the most popular material used in this process because it is a versatile engineering thermoplastic that can be used for both functional prototype and end-use production. Nylon is great for complex assemblies and long-lasting parts that are resistant to the elements.
SLS 3D printed nylon parts are tough, durable, and long-lasting. The final components are impact-resistant and can withstand repeated use. 3D printed nylon parts that are biocompatible and resistant to a wide range of environmental conditions, including UV, light, heat, moisture, chemicals, temperature, and water.
Applications of SLS 3D Printing
SLS 3D printing accelerates innovation and helps firms in a variety of fields, including engineering, manufacturing, and healthcare.
1)Engineering: Take command of the full product development process, from initial concept design to ready-to-use product manufacturing:
