What Is SLS 3D Printing?

Selective Laser Sintering (SLS) is an industrial 3D printing process ideal for manufacturing end-use parts. In SLS 3D system, a laser selectively sinters polymer powder particles, fusing them together and building a part layer-by-layer. From SLS rapid prototyping to small-batch production, our SLS 3D printing facilities will allow you to produce highly accurate parts, with low cost and high quality comparable to injection molding.

SLS produces functional plastic parts with isotropic mechanical properties that can be used for detailed prototyping or end-use low-volume production.

Size of SLS 3D Printed Parts

The below table shows the size of the selective laser sintering SLS 3D printed parts we usually make. If you need a larger size, we can also help you achieve it.

SLS 3D Printing Design Guidelines

The following table summarizes the recommended and technically feasible values for the most common features encountered in 3D printed parts.

Feature Recommended Size
Unsuported Walls 1mm(0.040")
Supported Walls 0.7mm(0.030")
Minimum Detail Size 0.25mm(0.010")
Minimum Hole Size 1.0mm(0.040")
Moving Parts 0.5mm(0.020")between moving surfaces
Assembly Clearance 0.4mm(0.016")between mating surfaces
Max Wall Thickness 20 mm (0.8''). Thicker parts must be hollowed with and at least two escape holes for powder removal with a min. diameter of 8 mm (0.3'').

Surface Finishing Options for 3D Printing

If you need to improve the strength, durability, looks, and even functionality of your 3D-printed prototypes or production parts, surface finishing is necessary. Explore these custom finishing options and there must be one suits your project.



Material Compatibility




3d printing painting


Enhance the appearance of your 3D printed object with custom colors and finishes. Choose from a wide range of paints and coatings to achieve the desired look and feel.

Plastics, Metals 

Customization is Available

Gloss, semi-gloss, flat, metallic, textured

3d printing polishing


Achieve a smooth and glossy surface finish through mechanical polishing techniques. This process removes layer lines and imperfections, resulting in a refined appearance.

Plastics (PLA, ABS) and Resins


Smooth and Glossy

3d printing powder coating

Powder Coating

Apply a durable and protective powder coating to your 3D-printed part. This process involves electrostatic-ally applying a fine powder, which is then cured to create a tough and resistant finish.

Metals (Aluminum, Stainless Steel, Steel)

Standard, Metallic, and Custom Options.

Gloss or Semi-gloss

3d printing bead blasting

Bead Blasting

Utilize bead blasting to achieve a uniform and textured surface finish. This process involves propelling small abrasive particles at the surface of the object.

Metals (aluminum, steel, titanium) and Certain Plastics


Matte or Satin-like
