Selective laser sintering

SLS 3D printing is the ideal solution for producing functional products with complex geometries. The technology has very few design constraints when compared to other 3D printing technologies and is also suitable for of batch manufacturing. The laser is aimed automatically at points in space defined by a 3d model, binding the material together to create a solid structure .The process begins by spreading an initial layer of powder over the build platform. The cross-section of the part is scanned and sintered by the laser, solidifying it. The build platform then drops down one layer thickness and a new layer of powder is applied. The process repeats until a solid part is produced.

The most common material for selective laser sintering is nylon, a popular engineering thermoplastic with excellent mechanical properties. Nylon is lightweight, strong, and flexible, as well as stable against impact, chemicals, heat, UV light, water, and dirt.

The combination of low cost per part, high productivity, and established materials make SLS a popular choice among engineers for functional prototyping, and a cost-effective alternative to injection molding for limited-run or bridge manufacturing.

Design Guidelines For Selective
laser sintering

Suggested minimum wall thickness 1.2mm
Maximum wall thickness 20mm
Un-supported wall thickness 0.8mm
Minimum Feature size 0.8 μm
Minimum hole size 1.5mm

Selective laser sintering Key Design Considerations

Wall thickness - The minimum wall thickness to ensure a successful 3D print varies between 0.8 mm (for PA12) up to 2.0 mm (for carbon filled polyamide).

Hole size - All holes should be larger than 1.5 mm diameter.

Escape holes must be a minimum of 3.5 mm diameter.

Feature size (pins, protruding features etc.) - A minimum size of 0.8 mm is recommended.

Tolerances - Typical tolerances for SLS parts are ± 0.3 mm or ± 0.05 mm/mm, whichever is greater.

Embossed and engraved details- Minimum depth of engraving 1 mm, Minimum height of embossing 1 mm
