Selective Laser Sintering (SLS) is an advanced 3D printing technique that uses a laser to selectively sinter thermoplastic powder, layer by layer, to create strong and durable parts. The process eliminates the need for support structures, making it ideal for intricate, production-ready components.
SLS uses a powder-bed approach, where a thin layer of powder is spread over the build platform, and a laser selectively fuses the powder to form the part layer by layer.
A high-powered laser heats and melts the thermoplastic powder in precise areas, creating a solid part with excellent detail and strength.
Unlike other 3D printing technologies, SLS parts do not need external support structures, as the surrounding powder acts as a natural support during the printing process. This reduces post-processing time and improves part accuracy.
Selective Laser Sintering (SLS) offers precise control over dimensional tolerances, layer resolution, and part sizes. Our advanced SLS technology ensures high accuracy, minimal warpage, and reliable part quality, making it ideal for both prototypes and production parts.

| Hole Diameter Recommendations | Minimum hole diameter: 0.5 mm (recommended 0.020”/0.50 mm), with consideration for reliable chip evacuation. |
| Clearance for Moving Parts | Ensure clearance of at least 0.5 mm between moving parts to avoid interference and improve part functionality. |
| Nesting & Volume Optimization | Optimize part orientation and packing to minimize material usage and reduce print time. Efficient nesting improves overall part quality. |
| Internal Radii | Avoid sharp internal corners; recommended radius: 2.6 x tool diameter to ensure proper sintering. |
| Thread & Tapped Holes | For threads Ø1.5-6 mm: depth = 3x diameter. For Ø6 mm: depth = 4x diameter. Custom threads available on request. |
| Surface Finish Requirements | Choose appropriate finish types (e.g., As-sintered, Bead Blasted) to meet functional and aesthetic needs. |
| Text & Engraving | Recommended text depth: minimum 0.6 mm width and 0.1 mm depth, especially for turned or finer marking. |
| Avoid Over-Constraint | Parts should not require excessive fixturing. Design for stable flat surfaces and supported geometries. Avoid ultra-thin features. |
| DFM Review Available | Our engineers will review your design for manufacturability, tool access, and stability to ensure efficient printing. |
