How it works

  1. 1

    Export logo as PNG

    Transparent background helps FlatStack detect shapes.

    Open FlatStack

    Quantize colors to your available filaments.

  3. 3

    Set real-world size

    Match coaster, badge, or card dimensions in millimeters.

    Export and print

    Use brim for small parts; sand the front face if needed.

Export formats
