Failed prints, supports, and leftover filament can add up quickly. Before you throw them away, it is worth looking at whether the material can be recycled or put to use in another project.
In this MakerBuildIt video, we explore why recycling 3D printer filament is not a simple yes-or-no question and share ideas for getting more use out of printing leftovers.
Recyclable material needs a suitable recycling process
The video discusses ABS and PLA as thermoplastics: materials that can be melted and reshaped. That makes reprocessing possible, but it does not mean your local recycling collection accepts failed prints or filament scraps.
Check with the receiving recycler before putting 3D printing waste in a collection bin. Prusa’s guide to recycling 3D printing waste explains the collection and sorting challenges and points to specialist recycling projects. It also clarifies that PLA does not belong in ordinary garden compost.
Look for a specialist filament recycler
One option covered in the video is finding a company that processes thermoplastics into material for new filament. Before sending scraps, confirm which materials the company accepts and how it wants them prepared.
Using recycled filament for new projects is another way to support the reuse of printing material.
Reuse failed prints and leftover filament
The video suggests repurposing pieces of failed prints as parts for other projects. A print that did not work for its original purpose may still contain something useful.
Other ideas include small items such as jewelry, coasters, ornaments, and keychains. Think about what you can make from the material you already have before starting with a new spool.
Reprocessing takes equipment and knowledge
Melting and reshaping scraps is another possibility discussed in the video, but it requires specialized equipment and knowledge. It is a different process from simply collecting leftovers for reuse.
Start by identifying your material, checking suitable recycling options, and looking for practical ways to reuse what remains.
