SLS (Selective Laser Sintering) is a powder-based fusion technique that uses a laser beam to sinter polymer powder, layer by layer, to create parts. A recoating blade puts an extremely thin layer of powdered material (nylon or polyamide) (0.1 mm) onto the build platform after it is heated at high temperatures in the overflow bin. After that, the building platform scans a whole cross-section, lowering the platform by one layer thickness.
The unsintered powder will stay in the same place to support subsequent layers, eliminating the requirement for support structures. The recoating blade applies another layer of powder on top of the previously scanned layer. The laser beam then sinters the cross-section part onto the previously solidified cross-section. This process is repeated until the part is finished.
SLS is required for users seeking a solution for manufacturing functional goods with complex geometries. This technology has little to no restrictions compared to other 3D Printing Services.
Powder Bed: A bed of powdered material is spread evenly
Laser Sintering: A laser selectively fuses the powder particles together, layer by layer
Layer Formation: The process is repeated, building the part layer by layer
Nylon12: Nylon 12 parts have good long-term stability, offering resistance to most chemicals. This material delivers the impact strength and durability required for functional testing. Tensile and flexural strength combine to make tough prototypes, with the flex associated with many production thermoplastics.
Glass-Filled Nylon (PA-GF): This glass-filled variant of Nylon 12 provides greater rigidity - perfect when prototyping parts requiring greater stiffness than standard Nylon 12. The filler in this material is glass beads, not fiber, resulting in increased stiffness but not strength

Industrial: SLS is used in various industrial applications, such as producing complex components and tooling
Additionally, the number of materials that may be used in SLS production is constrained, making it unsuitable for many applications. We manufacture your parts according to strict manufacturing standards. Verification of these requirements is included in our inspection report that is shipped with every order.
