Several software tools are used for 3D printing. Computer-Aided Design (CAD) software, such as Autodesk Fusion 360, SolidWorks, and Tinkercad, enables the creation and modification of 3D models. Slicing software, including Ultimaker Cura, PrusaSlicer, and Simplify3D, converts 3D models into printable instructions by generating the necessary toolpaths. MeshLab and Netfabb are used for mesh repair and analysis. Meshmixer and Autodesk Netfabb assist in preparing and optimizing models for 3D printing. Additionally, some 3D printer manufacturers offer their proprietary software, often including slicing capabilities tailored to their specific printers. The choice of software depends on the user's requirements and expertise.
