    Selective Laser Sintering (SLS) uses a high-power laser to sinter powdered material and build a solid and stable structure. SLS does not require support structures, which allows the construction of complex designs. Parts printed can work well as functional parts. Upload your CAD files and get the instant quotation within 1 second.

    SLS Post-processing

    We provide a wide range of post-processing options, making it possible to achieve the desired outcome.

    1. Threading

    Insertion thread is a metal fastening element that is inserted into an object to provide a threaded hole for fasteners such as screws or bolts.wenext

    2. Tapping

    Tapping is a machining process of cutting a thread inside a hole to produce internal threads.

    3. Sanding

    Sanding is a process to smooth the printed part and remove blemishes and leftover support marks.

    4. Painting

    Color printed part according to your desired outcome by selecting from the Pantone color chart.

    5. Grinding

    Grinding can be an effective solution to meet final tolerances.
