Selective Laser Sintering (SLS) is an advanced additive manufacturing technology that uses a high-powered laser to fuse small particles of polymer powder into a solid structure based on a digital model. The process involves spreading a thin layer of powder onto a build platform, where the laser selectively sinters (or melts) the material according to the CAD design. This is repeated layer by layer until the final part is created. SLS is known for producing highly durable, detailed, and complex components without the need for support structures, making it ideal for functional prototypes, end-use parts, and low-volume production.

SLS 3D printed parts typically exhibit excellent mechanical properties, including high strength, good impact resistance, and durability. The exact properties depend on the material used, but common SLS materials like nylon (PA12) offer strengths comparable to injection-molded parts. The parts are also resistant to wear and chemicals, making them suitable for functional prototypes and end-use applications. The mechanical properties can vary based on the specific material (if reinforced for example) used and post-processing treatments.
SLS parts typically achieve dimensional tolerances of ±0.3% with a minimum of ±0.3 mm. The accuracy can vary depending on factors such as part geometry, size, and post-processing steps. Smaller and simpler geometries tend to achieve tighter tolerances, while larger and more complex parts may experience slight deviations. For high-precision applications, it is advisable to consult with our team for specific tolerance capabilities.
SLS offers significant design freedom, but there are still some constraints to consider:
- Minimum Wall Thickness: Generally, walls should be at least 1-2 mm thick to ensure structural integrity, but it is possible to print wall thickness and details small as of 0.8.
- Holes and Channels: Small holes (less than 2 mm in diameter) may not fully form or may require post-processing. Internal channels should have a minimum diameter of 5 mm to ensure proper powder removal.
- Overhangs and Bridges (unsupported features): SLS doesn't require support structures, and can handle overhangs better than some other methods, but large unsupported features may need design consideration to avoid warping or weak spots.
- Interlocking Parts: Allow for sufficient clearance (typically 0.5-0.7 mm) between moving parts to prevent fusing during the sintering process.
- Surface Finish: Parts may have a slightly rough and grainy surface texture due to the nature of the powder-based process. The parts generally have around 6-12 µm Ra (roughness average). While the surface is functional and suitable for many applications, additional post-processing steps can be applied to achieve a smoother finish or specific aesthetic requirements.
