Our SLS Capabilities

Zero supports. Infinite freedom.

Design without constraints. Because SLS utilizes a self-supporting powder bed, it completely eliminates the need for support structures. This allows our engineers to print highly intricate internal geometries, nested assemblies, and complex overhangs that are otherwise impossible to manufacture, giving you absolute geometric freedom.

SLS 3D Printers that we used

Precision laser optics. Flawless execution.

Precision-guided accuracy. Our fleet of industrial SLS systems employs high-velocity CO2 lasers that meticulously sinter powder layer by layer within a tightly controlled thermal chamber. This precise thermal and optical management results in exceptional layer adhesion, minimal warping, and parts with outstanding mechanical reliability.

The SLS Gallery

Complexity, beautifully realized.

Step into a gallery of unconstrained design. This showcase highlights the pure versatility of SLS printing, featuring everything from intricate lattice structures and lightweight aerospace components to robust, flight-ready functional prototypes. See how the absence of supports unlocks a new dimension of design optimization.

Post-Processing for SLS

Meticulously cleared. Perfectly refined.

Elevating performance through precision finishing. Our SLS post-processing suite includes automated de-powdering, high-pressure bead blasting, and precision sorting. To tailor your parts for the field, we also offer custom surface sanding, structural coatings, and specialized dyeing to achieve the exact tactile and chemical properties your workflow requires.

Frequently asked questions

What is SLS 3D printing?

SLS (Selective Laser Sintering) uses a CO2 laser to sinter nylon powder layer by layer inside a heated chamber, producing strong, functional parts.

What are the advantages of SLS?

Because the powder bed supports the part, SLS needs no support structures. That allows intricate internal geometries, nested assemblies and complex overhangs, and makes SLS cost-effective for batch production of durable nylon parts.

Which SLS materials do you offer?

We offer PA11, PA12, glass-filled PA6 and PA12, carbon-filled PA6, PEEK 5100, polypropylene (PP), TPU and castable polystyrene (PS).

How fast is your SLS 3D printing service?

SLS parts can be ready in as little as 7 days, depending on part size, quantity and finishing.

What finishing options are available for SLS parts?

We de-powder and bead-blast every SLS part, and also offer surface sanding, structural coatings and dyeing.

SLS vs. MJF: What’s the Difference?

SLS nylon parts in the powder bed
SLS parts in the powder bed
HP Multi Jet Fusion nylon parts in the build unit
MJF parts in the build unit

SLS and MJF are both powder bed fusion processes for nylon and other plastic powders. The difference is how each layer is fused:

  • SLS (Selective Laser Sintering) — a laser traces the outline of each layer, fusing the powder point by point.
  • MJF (HP Multi Jet Fusion) — print heads apply a fusing agent where the part should be solid and a detailing agent around the edges, then heat fuses the whole layer at once.

What they have in common: the loose powder supports the parts as they print, so neither needs support structures. Both handle complex shapes, print many parts together in one build, and produce strong, functional parts. Both offer PA11, PA12 and flexible TPU.
