How to Remove Supports From 3D Prints

3D printing has revolutionized the manufacturing industry, making prototyping and creating custom designs easier than ever before. However, as with any technology, there can be some challenges along the way. One such challenge is removing the supports from 3D prints. Supports are necessary structures that are printed along with the model to provide stability during the printing process, but they can be difficult to remove without damaging the finished product.

In this post, we’ll guide you through the best practices for removing supports from 3D prints.

1. Choose the Right Support Material

Support materials come in a variety of types, including breakaway, dissolvable, and soluble. Breakaway supports are the easiest to remove but can leave marks on the model. Dissolvable supports are perfect for intricate designs but require more time and effort to remove. Soluble supports are the most complex but can be removed easily with the right tools. When choosing support materials, it is essential to consider the design of the model and the level of support required.

2. Use the Right Tools

The right tools are crucial for removing supports without causing damage to the model. A pair of pliers, a razor blade, or a hobby knife can all be useful for removing supports. However, it is essential to be careful when using these tools to avoid damaging the model. A good rule of thumb is to start with the smallest tool possible and work your way up if necessary.

3. Adjust the Slicing Settings

The slicing settings in your 3D printing software can impact the quality and ease of support removal. Consider adjusting the support density, infill density, and layer height to make support removal easier. Additionally, raising the temperature of the bed or extruder can make supports easier to remove.

4. Soak the Model

For models with dissolvable or soluble supports, soaking the model in warm water can make the removal process much easier. The water should be at a temperature of around 70 degrees Celsius, and the model should be soaked for around 12-24 hours. Any leftover supports can then be removed with a soft brush or a toothbrush.

5. Clean Up the Model

Once the supports are removed, it is essential to clean up the model to remove any remaining marks or residue. This can be done with sandpaper, a file, or a polishing wheel. The goal is to leave the model looking smooth and polished, ready for use or further customization.


Removing supports from 3D prints can be challenging, but with the right tools and techniques, it can be done quickly and easily.

Choose the right support material, use the right tools, adjust the slicing settings, soak the model if necessary, and clean up the model once the supports are removed. By following these steps, you can ensure that your finished product looks perfect every time.

Whether you’re a professional maker, hobbyist, or just starting out, knowing how to remove supports from 3D prints is an essential skill to have.
