If you’re familiar with 3D printing, you may have heard of Selective Laser Sintering (SLS), a popular additive manufacturing technique that can produce complex and functional parts. SLS is a powder-based 3D printing process that uses a laser to selectively fuse polymer powder into a solid part, layer by layer. In this article, we’ll take a closer look at how SLS works and why it’s a popular choice for both prototyping and end-use production.
Thermal Energy Binding
The SLS process starts with a bed of polymer powder, typically nylon or other thermoplastic materials. A laser beam is then used to selectively melt and fuse the powder in a specific pattern defined by the 3D CAD model. As the laser scans the bed, it heats and fuses the powder particles together to create a solid layer of the part. The process is then repeated layer by layer until the part is complete.
The benefit of this technique is that the parts do not require any support structures during the printing process. The powder itself acts as a support for any overhanging parts and undercuts, which reduces the need for post-processing. This process also allows for a high level of complexity in designs with minimal limitations on the geometry of the parts that can be produced.
Powder Recycling
SLS uses a bed of loose powder, which provides an advantage in terms of material usage and cost-effectiveness. The powder that is not sintered acts as support, meaning that less material is wasted than in other 3D printing techniques that require support. After the part is printed, the unsintered powder can be recycled and used for future builds, reducing material waste and cost.
High-Quality Parts
SLS is capable of producing parts with a high level of resolution, surface finish, and edge definition. The process is ideal for creating functional parts with complex geometries and can be used for both prototyping and end-use production. The parts produced using SLS are strong and durable and can withstand harsh environments. They can be finished with a variety of post-processing techniques, including dyeing, sanding, and smoothing, to achieve the desired surface finish and appearance.
