Discover the LS Technology

Create Production Parts, Functional Prototyping and ECS Ducting

What is LS?

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.

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.

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.

ECS Ducting

LS produces strong, complex ducts with interior features using FST-rated materials with superior heat resistance.

Challenges when designing environmental control systems can stem from the complexity of component configuration, geometrics and weight requirements. LS can solve this with strong, complex geometries quickly utilizing exceptional FST-rated materials like Nylon 12 FR.
