Easy Steps: How to Remove Supports from a 3D Print

Posted by

Removing supports from a 3D print can be a tricky task, especially if you are new to 3D printing. Supports are structures that are printed to provide stability to the model during the printing process. Once the print is complete, these supports need to be removed to reveal the final product. However, removing them incorrectly can damage the print, leaving you with a less than perfect result.

To remove supports from a 3D print, you will need a few tools, including pliers, a hobby knife, and sandpaper. The first step is to identify the areas where supports have been printed. Once you have located them, use the pliers to gently pull them away from the print. Be careful not to apply too much force, as this can cause the print to break or become deformed.

After removing the bulk of the supports, you will need to use a hobby knife to remove any remaining bits. This requires a steady hand and patience, as you want to avoid cutting into the actual print. Once all the supports have been removed, use sandpaper to smooth out any rough edges left behind. With a bit of practice, you can remove supports from your 3D prints with ease, leaving you with a professional-looking final product.

Why You Need to Remove Supports

Supports and Their Importance

When it comes to 3D printing, supports are an essential part of the process. These structures are necessary to hold up overhanging parts of a print that would otherwise droop or sag during the printing process. Supports are usually made of the same material as the print itself, and they are created as part of the same printing process.

However, once the print is complete, these supports are no longer needed and should be removed. There are several reasons why removing supports is important:

  1. Aesthetics: Supports can leave behind marks or blemishes on the surface of the print, which can detract from its appearance. Removing the supports can help to create a cleaner, more polished look.

  2. Functionality: In some cases, supports can interfere with the functionality of the print. For example, if the supports are not removed from a 3D printed gear, it may not rotate properly.

  3. Safety: In certain situations, supports can pose a safety hazard. For example, if a support is left inside a hollow part of a print, it could potentially cause a blockage or obstruction.

Overall, removing supports is an important step in the 3D printing process. By taking the time to carefully remove these structures, you can ensure that your prints look great, function properly, and are safe to use.

How to Remove Supports from a 3D Print

Materials You Need

Before you start removing supports from your 3D print, you will need a few materials. Here is a list of items you will need:

  • Pliers
  • Flush cutters
  • Sandpaper (220 grit)
  • Safety glasses
  • Dust mask

Step-by-Step Guide to Removing Supports

  1. Start by inspecting your 3D print. Identify the areas where support material is attached to your print. Make sure you have a clear understanding of the support structure before you begin.

  2. Put on your safety glasses and dust mask. This will protect your eyes and lungs from any debris that may fly off during the removal process.

  3. Use your pliers to grip the support material as close to the print as possible. Gently twist and pull the support material away from the print. If the support material is difficult to remove, you can use your flush cutters to snip away small sections of the support material until it is easier to remove.

  4. Once you have removed all of the support material, use your sandpaper to sand away any remaining bumps or rough spots on your print. Be careful not to sand away any of the details on your print.

  5. If you have any hard-to-reach areas, you can use a dental pick or similar tool to remove the support material.

  6. Once you have finished sanding your print, inspect it again to make sure all of the support material has been removed. If you find any remaining support material, repeat steps 3-5 until it is completely removed.

And that’s it! With a little bit of patience and some careful attention to detail, you can easily remove support material from your 3D prints.

Tips and Tricks

Removing Difficult Supports

Sometimes, removing supports from a 3D print can be a difficult and frustrating process. Here are some tips to make it easier:

  • Use a pair of pliers or tweezers to grip the support and wiggle it back and forth gently. This can help loosen it from the print.
  • If the support is particularly stubborn, try using a hobby knife or scalpel to carefully cut away at it. Be careful not to damage the print itself.
  • For supports that are hard to reach, try using a heated tool like a soldering iron or heat gun to soften the support material. This can make it easier to remove.

Post-Processing Your 3D Print

After removing the supports, you may want to do some post-processing to clean up your print and give it a more polished look. Here are some options:

  • Sanding: Use sandpaper or a sanding sponge to smooth out any rough or uneven areas on your print.
  • Painting: If you want to add some color to your print, consider painting it with acrylic or spray paint.
  • Filling: If there are any gaps or holes in your print, you can use a filler material like Bondo or epoxy putty to fill them in.

Remember to always wear gloves and protective eyewear when handling chemicals or tools. With a little patience and some practice, you can remove supports and post-process your 3D prints like a pro.


Removing supports from 3D prints can be a daunting task, but with the right tools and techniques, it can be done with ease. In this article, we have covered several methods for removing supports, including manual removal, using pliers, and using a heat gun.

When manually removing supports, it is important to take your time and be patient. Use a pair of flush cutters to snip away at the supports, being careful not to damage the print itself. If you are having trouble reaching certain areas, try using a pair of angled cutters.

Pliers can also be a useful tool for removing supports, especially if they are in hard-to-reach areas. Use needle-nose pliers to grab onto the supports and gently wiggle them back and forth until they break away from the print.

If you are dealing with supports that are particularly stubborn, a heat gun can be a great solution. Use the heat gun to soften the supports, making them easier to remove. Be careful not to overheat the print, as this can cause warping or other damage.

Overall, the key to successfully removing supports from 3D prints is to be patient and take your time. With the right tools and techniques, you can achieve a clean and professional-looking finish on your prints.
