    Understanding STL Files and the Need for Repairing

    An STL file is a commonly used format for 3D printing that represents the geometry of a three-dimensional object. However, these files can often have issues such as intersecting or overlapping geometry, non-manifold surfaces, and gaps in the mesh.

    Therefore, it becomes necessary to repair these STL files before they can be successfully printed.

    What is an STL file?

    An STL file is a type of file that 3D printers use. It stands for “stereolithography“. These files hold the shape of a 3D object. The printer reads this file to know how to make the item.

    People who create with 3D printers must fix STL files sometimes. They might not work well with the printer or they may have other issues. Tools like Meshmixer can help solve these problems and get the model ready for printing.
