Interlocking Joints

Definition

Interlocking joints are connection features used in assembly that allow two or more parts to fit together securely without the need for additional fasteners. These joints rely on geometric shapes that enable parts to resist movement and maintain structural integrity, making them particularly useful in 3D printing where assembly precision is crucial. Their design can optimize material usage and improve ease of assembly, which is essential for efficient production processes.
