CREATING A SPRING IN FREECAD 1.0 : HOW TO MODEL A SPRING IN 3D | MAKING A SPRING IN 3D WITH FREECAD

Creating a spring in 3D is a useful skill, especially for those interested in mechanical design or 3D printing. One of the best tools for this task is FreeCAD, an open-source parametric 3D modeling software. Learning how to create a spring in FreeCAD involves using the right workbenches and tools. The most common method starts with the Helix tool in the Part or Draft workbench. To make a spring in FreeCAD, you typically define the helix parameters—such as pitch, height, and radius—and then create a circular profile that represents the cross-section of the wire. Using the Sweep function, you then sweep this circle along the helical path to form the spring.
Knowing how to make a spring in FreeCAD is beneficial because it allows you to tweak parameters easily. For example, if you're designing a compression spring, you might adjust the number of turns, the diameter, or the wire thickness. Once the spring is designed, you can export it as an STL file for 3D printing. However, 3D printing a spring comes with limitations. While creating a spring in 3D is straightforward, materials like PLA or ABS might not offer the elasticity needed for functional springs. Flexible filaments like TPU are more suitable for working prototypes. When 3D printing a spring, consider print orientation, layer height, and infill to ensure durability.
Whether you're just learning how to create a spring in FreeCAD or already comfortable making a spring in FreeCAD, this project is a great way to explore both modeling and prototyping. With practice, you’ll find it easy to make a spring in FreeCAD that meets your design needs, and even experiment with different types of springs for various applications.
