Selective Laser Sintering (SLS)

Get parts that have excellent long-term stability and resistance to most chemicals, ideal for tooling, fixtures and low-volume production

Functional Parts

Selective Laser Sintering technology offers fully functional prototypes with strong mechanical properties and good thermal resistance

All Stages of Product Lifecycle

This robust process can build parts for all stages of the production lifecycle, from prototyping to low-volume manufacturing opportunities.

Strong Production Parts

SLS production parts can be strong, water and air-tight and made out of engineering-grade thermoplastics

Why choose Selective Laser Sintering?

Parts produced with Selective Laser Sintering (SLS) technology can rival injection-molded and machined plastic parts, with excellent mechanical properties and chemical resistance. SLS is an extremely versatile method that can work for a huge variety of materials, from very stiff to flexible. Because there’s no need for support structures, SLS printing is a good choice for producing very complex geometries.

SLS is commonly used for functional prototypes, tooling, fixtures, design evaluation models, small manufacturing runs, and product testing. SLS parts have been flight-certified and are being used today in civil and military aircraft around the world.

How does it work?

Laser Sintering, also known as Selective Laser Sintering (SLS), builds with a CO₂ laser that melts cross-sections of a CAD design in powdered material.

While being built, LS parts remain encased in an unsintered powder bed, replacing the need for support structures.

Without support structures, designers can easily add undercuts and internal features and reduce post-processing time.

Engineering-grade materials

LS provides a full range of engineering-grade thermoplastics well-suited for high requirement applications.

Long use cycles and part fatigue have met their match. Depend on standard Nylon 11 and Nylon 12 materials and variety of reinforced nylons with property-enhancing fillers for light-weight, highly durable and heat and chemical resistant parts.

Prototypes to Production Parts

This robust process can build parts for all stages of the production lifecycle, from prototyping to low-volume manufacturing opportunities.

LS builds robust parts with filled Nylon materials, making it an ideal process for applications such as duct work, fuel tanks and brackets, as well as functional prototyping.

What is SLS?

Selective Laser Sintering (LS) is a way to build prototypes early in the design cycle or production parts in a wide variety of applications.

LS production parts are strong, water and air-tight, heat resistant and repeatable. This robust process can build parts for all stages of the production lifecycle, from prototyping to low-volume manufacturing opportunities.
