OVERVIEW

    Create Complexity with LS

    Laser Sintering (LS) is a way to build prototypes early in the design cycle or production parts in a wide variety of applications. Laser Sintering (LS), also known as Selective Laser Sintering (SLS), creates tough and geometrically complex components for batch or serial manufacturing in a wide variety of applications. LS production parts are strong, water and air-tight, heat resistant and repeatable.

    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.

    Go Beyond Conventional

    With the ability to produce complex features, under cuts and internal structures, LS can consolidate multiple components with ease.

    Create Complexity with LS

    LS 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.

    Quality Assurance

    Our quality systems ensure consistent handling and recycling of materials along with machine maintenance and process control limits. This provides material traceability, mechanical property verification, dimensional and other performance criteria checks to ensure the parts we deliver meet customer specifications repeatedly.

    Engineering-Grade Materials

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

    FAQ's

    Frequently Asked Questions

    What geometries are best suited for LS?

    LS is ideal for components with extremely complex geometries, including parts with internal cavities. Parts that are produced with LS remain encased in powdered material, which is self-supporting thereby eliminating the need for additional supportive structures on or within the components.

    What level of detail can be obtained with LS?

    Laser Sintering can produce a layer thickness of 0.004”- 0.006” and an X/Y resolution of 0.030” – 0.050”. We recommend all LS parts have a minimum wall thickness of 0.040”. See the LS design guidelines for more details.

    What is the largest part size you can make with LS?

    The build platform for our largest LS machine is 26.5”x13.5”x20”. Parts that exceed those dimensions can be built in sections and bonded. Bonding lines introduce a degree of consistency in regards to mechanical performance.
