SLS 3D Printing

High-Precision Prototyping & Production

Selective Laser Sintering (SLS) is a cutting-edge 3D printing technology that uses a high-powered laser to fuse powdered materials, producing strong and durable parts with intricate details. This method is widely used for functional prototypes, end-use parts, and low-volume production in industries such as aerospace, automotive, medical, and manufacturing.

Why Choose SLS?

    • Produces high-strength, durable prototypes that mimic real-world performance.

    • Used by industries such as aerospace, automotive, and medical for rigorous testing.

    • Cost-effective for small to medium production runs.

    • Ideal for custom or personalized parts, including medical devices and consumer goods.

    • Can create intricate internal structures, lattice designs, and lightweight components.

    • Critical for aerospace and automotive applications where performance is key.

    • High mechanical strength, impact resistance, and heat resistance make SLS parts ideal for real-world applications.

    • Used in automotive, manufacturing, and tooling for parts that need to withstand extreme conditions.

How SLS Works

  • Powder Bed

    A fine layer of powder (typically nylon) is spread evenly across a build platform.

  • Laser Sintering

    A high-powered laser scans the powder bed, fusing particles together layer by layer.

  • Layer-by-Layer Build

    The process continues until the entire part is formed.

  • Finished Part

    Once the build is complete, the part is removed from the powder bed, cleaned, and post-processed as needed.

Materials Available for SLS

  • Nylon 12

  • Nylon 12GF

  • Nylon TPU 90 (Available Upon Request)

Industries & Applications

    • Why it fits: Lightweighting is crucial in aerospace, and SLS excels at creating complex, hollow structures and lattice designs that are strong yet lightweight. It's also great for custom parts and low-volume production, common in this industry.

    • Examples: Ducting, brackets, housings, even parts for rocket engines.

    • Why it fits: Similar to aerospace, automotive needs strong, lightweight components. SLS is used for functional prototypes that mimic end-use parts, as well as for creating custom or low-volume production parts.

    • Examples: Housings, brackets, ducts, jigs and fixtures for manufacturing.

    • Why it fits: SLS offers high precision and can work with biocompatible materials, making it ideal for patient-specific devices.

    • Examples: Custom prosthetics, orthotics, surgical guides, implants.

    • Past Clients: Tulane University Biomedical Research Center, Innogenomics, Oschner Baptist Medical, Quick Take Health

    • Why it fits: SLS produces durable parts suitable for tooling, jigs, and fixtures used in manufacturing processes. It's also cost-effective for low-volume production or bridge manufacturing (filling the gap between prototyping and mass production)

    • Examples: Custom tools, fixtures for assembly lines, end-of-arm tooling for robots.

    • Past Clients: Latrium/Intralox, Acadian Millwork, Advanced Cutting Solutions, America Best Signs, Functions Engineering, Geoshields, Global Star, Indigo Papers, Sweet Bay Studios, Terracon, Trayaway, Striker VR, Webbrite Safety, Thompson Equipment Company

    • Why it fits: Intricate designs, low cost that is paintable for sets, props, etc.

    • Examples: Universal Studios & Various Production Companies

    • Past Clients: Jurassic Park, I am Virgo, Twisted Metal, The Winchesters, The Legend of Bagger Vance
