Selective Laser Sintering
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 Selective Laser Sintering
Below table shows the size of selective laser sintering parts we usually make. If you need a larger size, we can also help you achieve it.

Design Guidelines of Selective Laser Sintering
The following table summarizes the recommended and technically feasible values for the most common features encountered in 3D printed parts.
| Feature | Recommended size |
| Unsupported walls | 1.0 mm (0.040'') |
| Supported walls | 0.7 mm (0.030'') |
| Minimum detail size | 0.25 mm (0.010'') |
| Minimum hole size | 1.0 mm (0.040'') |
| Moving parts | 0.5 mm (0.020'') between moving surfaces |
| Assembly clearance | 0.4 mm (0.016'') between mating surfaces |
| Maximum 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''). |

Painting
Painting the surface of a part improves its aesthetic appearance and can provide brand recognition to consumers. In addition, painting can have a protective effect on parts.
Aluminum, Stainless Steel, Steel
Black, any RAL code or Pantone number
Gloss, semi-gloss, flat, metallic, textured
Polishing
Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.
Aluminum, Brass, Stainless Steel, Steel

Powder Coating
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.
Aluminum, Stainless Steel, Steel
Black, any RAL code or Pantone number
Gloss or semi-gloss
Bead Blasting
Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.
ABS, Aluminum, Brass, Stainless Steel, Steel
