How to Prepare Your 3D Prints for Recycling
When it comes to recycling 3D prints, there are a few steps you need to take to ensure the process goes smoothly. In this section, we will go over the steps you need to follow to prepare your 3D prints for recycling.
Remove Support Structures
The first step in preparing your 3D prints for recycling is to remove any support structures. These structures are used to hold up overhanging parts of your print while it is being printed. They can be made of the same material as your print or a different material. Either way, they need to be removed before you can recycle your print.
To remove support structures, you can use a pair of pliers or a pair of snips. Carefully cut away the support structures, being careful not to damage the rest of the print. Once you have removed all the support structures, you can move on to the next step.
Separate Different Types of Filament
The next step in preparing your 3D prints for recycling is to separate different types of filament. If you have printed your object with multiple types of filament, you need to separate them before recycling. This is because different types of filament have different melting points and require different temperatures to be melted down.
To separate different types of filament, you can use a pair of snips or a sharp knife. Carefully cut away the different types of filament, being careful not to damage the rest of the print. Once you have separated all the different types of filament, you can move on to the next step.
Clean Your Prints
The final step in preparing your 3D prints for recycling is to clean them. This means removing any dirt, dust, or debris from the surface of the print. You can use a soft brush or a damp cloth to clean your prints.
Once your prints are clean, you can move on to the recycling process. The specific process you need to follow will depend on the type of material your print is made of. Be sure to follow the instructions carefully to ensure your prints are properly recycled.
In summary, to prepare your 3D prints for recycling, you need to remove support structures, separate different types of filament, and clean your prints. By following these steps, you can ensure that your prints are properly prepared for recycling and that they can be reused in new projects.
Methods of Recycling 3D Prints
There are several methods to recycle 3D prints, including mechanical recycling, chemical recycling, and upcycling.
Mechanical Recycling
Mechanical recycling involves grinding down used prints and filament into small particles, which can be melted down and reused. This method is the most common and straightforward way to recycle 3D prints.
To recycle 3D prints mechanically, you will need a filament extruder or a filament recycler. Filament extruders are designed to take your scrap 3D printing materials, including discarded filaments, misprints, random globs of plastic, and make repurposed filament out of them. Some models can even take and recycle plastic that are not necessarily associated with 3D printing, such as empty water bottles.
Chemical Recycling
Chemical recycling involves breaking down the plastic in 3D prints into its chemical components and then reusing those components to create new plastic. This method is more complex than mechanical recycling and requires specialized equipment and expertise.
One example of chemical recycling is depolymerization, which involves breaking down the plastic using heat and chemicals. This method can be used to recycle a wide range of plastics, including ABS, PLA, and PETG.
Upcycling
Upcycling involves repurposing used 3D prints into new objects. This method is the most creative and can result in unique and interesting creations.
One example of upcycling is to combine two or more prints into something new and unique. Consider combining something like a Yoda bust or low-poly Darth Vader into a new, unique figure. The best part is, you only need simple supplies such as glue or tape. This project totally depends on what you have available.
Another example of upcycling is using 3D prints as molds for other materials, such as concrete or plaster. This can result in unique and interesting shapes and textures that are not possible with traditional molds.
In conclusion, there are several methods to recycle 3D prints, including mechanical recycling, chemical recycling, and upcycling. Each method has its advantages and disadvantages, and the best method for you will depend on your goals and resources.

In conclusion, there are many options available for recycling your 3D prints. Whether you choose to take them to your local recycling center, use a specialized recycling service, or participate in a mail-in program, recycling your 3D prints is a great way to reduce waste and help the environment.
Conclusion
Recycling 3D prints is a great way to reduce waste and save money. There are several ways to recycle failed prints, including using a filament recycler, building something new with the failed prints, or making ABS juice. Each method has its own advantages and disadvantages, so it’s important to choose the one that works best for you.
Using a filament recycler is a great option for those who have a lot of failed prints. It grinds and melts the failed prints before extruding and coiling the filament onto a spool. Some filament recyclers only grind, while others only melt the waste, so you need two machines to recycle failed 3D prints. However, it’s important to note that recycled filaments tend to exhibit an overall decrease in tensile and shear strength compared to their virgin counterparts. Repeated recycling tends to magnify this decrease in quality, resulting in filaments that are progressively more brittle and frailer.
Building something new with the failed prints is a fun and creative way to recycle them. It allows you to turn your failed prints into something useful or decorative. You can combine two or more prints into something new or use them as building blocks for a larger project. This method doesn’t require any special equipment, but it does require some creativity and imagination.
Making ABS juice is another way to recycle failed prints. It involves dissolving the failed prints in acetone to create a liquid solution that can be used as an adhesive or coating. ABS juice is particularly useful for printing with ABS, as it helps the print adhere to the build plate and prevents warping. However, it’s important to use ABS juice in a well-ventilated area and to wear gloves and a mask, as acetone can be harmful if inhaled or absorbed through the skin.
Overall, recycling 3D prints is a great way to reduce waste and save money. Whether you choose to use a filament recycler, build something new with the failed prints, or make ABS juice, there are several ways to give your failed prints a second life.
