Stereolithography (SLA) 3D Printing Services

Ultra-High Resolution. Smooth Surface Finish
Precision Prototyping

Stereolithography (SLA) is a resin-based 3D printing technology renowned for its exceptional detail, surface quality, and accuracy. Ideal for visual models, tight-tolerance prototypes, and medical applications, SLA delivers parts that closely resemble injection-molded components—fast and affordably.

    What Is SLA 3D Printing??

    SLA uses a UV laser to cure liquid resin layer by layer into solid plastic parts. Because the laser operates with
    high precision, SLA can produce parts with ultra-fine features, smooth surfaces, and sharp edges. It’s the
    technology of choice when appearance, accuracy, and fine detail are critical.
    Whether you’re refining a concept, preparing for molding, or
    creating complex geometries for research or healthcare, SLA offers unmatched clarity and precision.

    Advantages of SLA Technology

    3D Printing

    Superior Surface
    Finish

    Parts printed with SLA have a smooth, almost glass-like surface straight out of the printer—ideal for visual and cosmetic prototypes.

    3D Printing

    Exceptional Detail and
    Accuracy

    Achieve sharp corners, thin walls, and intricate textures with layer resolutions as
    fine as 25 microns.

    3D Printing

    Ideal for Mold Making
    and Casting

    SLA is perfect for master patterns used in silicone molding or investment casting.

    SLA Applications

    • • Exceptional surface finish and fine feature resolution.
    • • Ideal for visual models, fit checks, and presentation parts.
    • • Available in various neutral and opaque colors.
    Tough & Durable Resins

    Tough & Durable Resins – Impact-Resistant Options for Functional Testing

    Tough and durable resins simulate the mechanical properties of ABS and polypropylene, providing resistance to impact, deformation, and stress. These materials are ideal for functional testing, jigs, fixtures, and parts that undergo mechanical loading.

    • • High elongation and tensile strength for mechanical parts.
    • • Resists cracking and deformation under load.
    • • Suitable for functional assemblies, snap fits, and tools.
    Clear Resins

    Clear Resins – Excellent Optical Clarity for Lenses and Fluidic Devices

    Clear resins offer high optical transparency and smooth surfaces, making them perfect for applications requiring light transmission or internal visibility. With polishing and coating, they can closely simulate glass or acrylic.

    • • High clarity for lenses, light guides, and microfluidics.
    • • Can be post-processed for increased transparency.
    • • Ideal for aesthetic parts requiring internal inspection.
    Flexible Resins

    Flexible Resins – Rubber-Like Materials for Gaskets, Seals, and Overmold Simulation

    Flexible SLA resins offer elastomeric properties with tunable softness, making them great for simulating rubber or silicone. They enable functional testing of parts requiring deformation, compression, or soft-touch characteristics.

    • • Shore A hardness typically between 50A–80A.
    • • Withstands repeated bending and compression.
    • • Used for seals, wearable components, and cushioning elements.
    High-Temp Resins

    High-Temp Resins – For Parts Exposed to Elevated Heat or Thermal Cycling

    High-temperature SLA resins are designed to maintain dimensional stability under extreme heat. They are ideal for functional prototypes and components exposed to hot environments or thermal stress during use or testing.

    • • Heat deflection temperatures up to 238 °C (post-cured).
    • • Suitable for hot-air ducts, fixtures, and molds.
    • • Maintains mechanical integrity under cyclic heat exposure.
    Biocompatible Resins

    Biocompatible Resins – Certified for Skin Contact, Dental, and Surgical Applications

    Biocompatible SLA resins are engineered and tested for use in medical and dental applications. They meet ISO 10993 and other regulatory standards, enabling safe use in contact with skin, gums, or surgical tools.
