    Creation

    Manual

    It is possible to design a 3D model from the ground up for 3D printing using standard 3D software.

    3D Scanning

    3D Scanning through techniques such as photogrammetry can be used to duplicate real world objects.[1]

    • A 3D Scanner that photographs objects as they move on a turntable.

    • A less common but quicker scanner type uses a chamber filled with cameras that surround the subject.

    Editing

    Some models, such as those created by 3D scanning, require cleanup before they can be printed.[2]

    3D models on a computer can represent things that are impossible to recreate in reality. Thus for a model to be 3D printable, it must represent an actual object, without errors in an object that would cause the interior of the model to not be watertight.[3]

    File Formats

    STL

    .stl has become a de facto standard for many 3D printer slicer programs.[4][5]

    3MF

    3MF is an open source format that offers a number of improvements over .stl, such as being more error resistant and including color information.[6][7]
