What happens when filament gets old?
Once this has happened, its effect is irreversible. The effects of this moisture breaking the long molecular chains results in a more brittle filament; it can even snap during feeding, leading to unpleasant results like unfinished prints.
What can I do with old PLA filaments?
How do you recycle it then? Search for an online filament recycler where you can send them your scraps and they will recycle it for you. It is also possible to compost PLA, either at an industrial facility or at home. This process is likely to take around 6 months.
How long does it take for PLA to go bad?
Within as little as a month, to up to two years, PLA will break down when exposed to the environment. While not soluble in water, PLA does absorb a lot of water.
Is there a way to reuse PLA?
The short answer is, you can definitely recycle PLA filament, but not in the same way you can recycle your milk jugs, food containers, and other types of everyday plastic. PLA has a lower melting point than other plastics, so it can’t go into the same bundle with the rest.
How can I tell if my filament is getting old?
If you do suspect that your filament has absorbed moisture, you can dry it out, by placing the spool in a warm oven or in a food dehydrator for a few hours. If you weight it before and after, you should find that it weighs several grams less afterwards.
What should I do if my printer filament is getting old?
Some people use “dry boxes” that allow the spool to be mounted inside while filament can be passed to the printer, so there is minimal exposure even while the spool is in use. If you do suspect that your filament has absorbed moisture, you can dry it out, by placing the spool in a warm oven or in a food dehydrator for a few hours.
What can you do with old filament spools?
Even the Filabot team has used old spools for other uses. While all of these solutions are a step in the right direction, there is more that can be done. The mountain of empty spools that is filling up your garage, office, or makerspace studio needs a loop closed.
Can you make filament out of old plastic?
Click the button below for a free sample of filament made from old filament spools! Each spool company and filament extrusion company uses a different grade of plastic. Knowing the grade or plastic of your spools will help to determine necessary temperatures to successfully print.
