Selective Laser Sintering (SLS) Capabilities
Selective Laser Sintering (SLS) is a powder bed fusion 3D printing technology where a laser selectively sinters (fuses) layers of powdered material. The most common material is nylon (PA12), but PA11, glass-filled nylon, TPU, and other polymers are available. SLS produces parts with excellent mechanical properties — comparable to injection-molded nylon in many respects. Because the unfused powder supports the part during building, SLS requires no support structures, enabling complex geometries including interlocking assemblies, living hinges, and internal channels. SLS is the most popular technology for functional prototyping and low-volume production of plastic parts.

Selective Laser Sintering (SLS) in Saint Louis — FAQ
How many Selective Laser Sintering (SLS) providers are in Saint Louis, MO?
The St. Louis metropolitan area has approximately 1,800 manufacturing establishments, many of which offer selective laser sintering (sls) services. The area employs about 42,000 manufacturing workers, ensuring a skilled workforce for your project.
How strong are SLS nylon parts?
SLS PA12 nylon parts have tensile strength of 6,500-7,200 PSI, elongation at break of 15-25%, and good impact resistance. These properties are comparable to injection-molded nylon, making SLS suitable for functional prototypes and end-use parts.
What is the surface finish of SLS parts?
SLS parts have a slightly grainy, matte surface texture with roughness of ~250-400 Ra microinches. Parts can be tumble-polished, vapor-smoothed, dyed, or painted for improved aesthetics. Vapor smoothing produces a near-glossy surface.
Can SLS parts be used outdoors?
SLS nylon parts have good UV resistance but will yellow and become brittle with prolonged sun exposure. For outdoor use, UV-stabilized materials, protective coatings, or dye (black absorbs UV) are recommended.
What is the minimum feature size for SLS?
Minimum wall thickness is approximately 0.030" (0.7mm). Minimum feature size is about 0.020" (0.5mm). Holes under 0.040" diameter may close during sintering. These limits depend on the specific machine and material parameters.
