SLS Printing

Selective Laser Sintering — production-grade nylon parts with no support structures, isotropic strength.

Material
Nylon PA12
PA12 nylon with 50% powder refresh rate. Tough, slightly flexible, excellent chemical resistance.
Accuracy
±0.3mm
High dimensional accuracy for functional assemblies and snap-fit mechanisms.
Support-Free
100%
Unsintered powder supports every surface — no support structures, no witness marks.
Density
>95%
Near-full density nylon parts with consistent isotropic mechanical properties.
SLS Advantages

No supports. No limits.
Just functional parts.

SLS uses a CO₂ laser to sinter powdered nylon layer by layer. Because unsintered powder surrounds the part, no support structures are needed — enabling complex geometries, internal channels, and interlocking assemblies printed in one build.

SLS parts are mechanically superior to FDM for most engineering applications and more cost-effective than SLA at production volumes.

Complex GeometryInternal channels, undercuts, hinges, and assemblies — all in one print, no assembly required.
Batch EfficiencyNest multiple parts in the build volume — more parts per build means lower cost per unit.
End-Use PartsSLS nylon is production-viable for brackets, housings, clips, ducts, and load-bearing components.
Surface FinishingTumble polishing, bead blasting, dyeing, and painting all compatible with SLS parts.
