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.

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.

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.

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.
