Selective Laser SINTERING (SLS)

Selective Laser Sintering
(SLS) 3D Printing

Selective Laser Sintering (SLS) is a powerful 3D printing technology trusted by engineers and manufacturers for producing high-strength, functional parts—without tooling or support structures. Ideal for both prototyping and end-use production, SLS offers design freedom, excellent mechanical properties, and scalability for a wide range of industries.

    What Is SLS?

    SLS is a powder bed fusion process that uses a high-powered laser to fuse nylon or composite powder layer by
    layer into solid parts. Because the unsintered powder supports the structure during printing, SLS can produce
    intricate, interlocking, and load-bearing parts without the need for support material—saving time and reducing
    post-processing effort.

    Key Advantages of SLS

    3D Printing

    Functional, Durable
    Parts

    SLS-printed parts are tough, chemically resistant, and ideal for real-world use in demanding environments.

    3D Printing

    Complex Geometries, No
    Supports

    Print moving assemblies, lattice structures, and nested components in a single build with no support cleanup.

    3D Printing

    High Accuracy &
    Repeatability

    Tight tolerances and consistent output across small batches and large runs.

    Nylon 12 Part

    Nylon 12 (PA12) – Strong, Durable, and Versatile for Most Engineering Needs

    Nylon 12 is the most commonly used material in SLS due to its balanced mechanical properties, chemical resistance, and dimensional stability. It is well-suited for functional prototypes, end-use parts, and components that need to maintain performance under stress.

    • • Excellent tensile strength and durability for repeated use
    • • Resistant to abrasion, chemicals, and environmental exposure
    • • Ideal for housings, connectors, brackets, and jigs.
    Nylon 11 Part

    Nylon 11 (PA11) – More Flexible and Impact-Resistant, Ideal for Living Hinges and Enclosures

    Nylon 11 offers greater elongation and toughness than PA12, making it ideal for parts that experience bending, impact, or snap-fit assembly. Derived from renewable castor oil, PA11 is also a more sustainable option.

    • • High ductility and fatigue resistance for dynamic applications
    • • Biocompatible and chemical-resistant for specialized environments.
    • • Great for enclosures, living hinges, protective covers, and wearables.
    Glass-Filled Nylon Part

    Glass-Filled Nylon – Increased Stiffness for Structural or Load-Bearing Parts

    Glass-filled Nylon blends standard PA12 with glass beads or fibers, significantly improving stiffness, dimensional stability, and heat resistance. It’s ideal for applications requiring rigidity and strength over long-term use.

    • • Enhanced modulus and dimensional accuracy for structural components.
    • • Reduces warping in large, flat parts during the printing process.
    • • Used for mounts, casings, jigs, and parts under mechanical load.
    Carbon-Filled Nylon Part

    Carbon-Filled Nylon – Lightweight, High-Strength Composite Material

    Carbon-filled Nylon combines nylon with carbon fibers to produce lightweight yet extremely strong parts with excellent thermal stability. It’s ideal for high-performance applications that require strength-to-weight optimization.

    • • Increased stiffness and strength with reduced part weight.
    • • Electrically conductive properties in some formulations.
    • • Ideal for aerospace fixtures, motorsports parts, and tools.
