How to reuse filament

Creating Recycled Filament There are two major parts of the process when it comes to recycling your own filament: shredding and extruding. The first part prepares plastic for melting, then in the second part, the shredded plastic is melted and re-shaped.

How do you melt and reuse filaments?

Get a Filament Recycler A recycler system is a great way to turn your excess filament or failed prints back into usable filament. The system grinds up and melts the plastic. Then extrudes it and coils it onto a spool. Many machines only grind or only melt, meaning you may need two machines.

Can you reuse PLA filaments?

Going Further. 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 do you reuse 3D printed filaments?

If you want to turn the material left over from your 3D prints back into material you can print on, there are currently three ways to do it: create your own filament, use a special extruder that allows you to print directly using recycled plastic pieces, or buy filament rolls made from recycled material.

What do I do with the last bit of filament?

Use it as regular filament with a 3D printer pen to fix 3D printed parts. "Use it for pin/studs/rivets/hinges in prints." as tjb1 said. Stock it with your failed/ waste 3D printed parts and use them in a recyclebot later to make new filament or simply melt it in an oven to make plastic boards/injection molding material.

Can I melt filament together?

The basic premise of filament welding is to join two different pieces of filament together to make one longer piece. This can be done with any of the most commonly used filament types (PLA, ABS, TPU, or PETG), but for the purposes of this discussion, we'll be looking at techniques for welding PLA.

Is 3D printing wasteful?

It uses only the exact amount needed in the exact way, so there's no need to carve or trim excess materials. As a result, there are exponentially fewer scraps. According to experts, 3D printing in the construction industry can reduce waste by 95% or more.

How many times can PLA be melted?

Biocompostable final product: yes, but only in special composting facilities (requires 55-60 degrees Celcius for at least 10 days). Hence the recycling recipe. Re-use: yes, it can be re-melted endlessly as long as the PLA is not combined with other materials in a composite.

What can I do with old spools of filaments?

Here are recycling ideas for your empty filament spools.

Spool organiser. Reduce the clutter at your workstation by creating compartments or organisers for small parts and accessories out of your empty spools.
Toys. You can give joy to kids and your feline babies using empty spools. ...
Shelving. ...
Lamp. ...
Cable reel. ...
Yarn Winder.

Does rubbing alcohol dissolve PLA?

For isopropyl alcohol, not all PLA will dissolve in this solvent. There are specially manufactured PLA from the Polymaker brand which can in dissolved isopropyl alcohol. Before trying it out, you should consider the kind of PLA being printed.

How long can PLA sit out?

PLA exposed to direct sunlight at ambient temperature can survive for 1 week then it becomes brittle. PLA filaments exposed to more than 60% humidity can be usable for less than a month but can produce bad prints.

How do you revive an old PLA filament?

Leaving PLA in a dry environment for a week or two should adequately re-dry it, or it can be gently heated to about 120F / 50C for a couple hours. (Some people dry it hotter. but that risks deforming the filament.) ABS also doesn't absorb very much water, but perhaps a little more than PLA.

Can you remelt 3D filament?

If you want to create your own circular economy for 3D printing materials, it is also possible to recycle 3D printer filament at home using a filament extruder. In the simplest terms, this piece of equipment is a machine that melts raw plastic pellets and extrudes the thermoplastic as a filament.

Do you remove filament after every print?

Most filaments you can leave in the extruder indefinitely without any ill effects. There are some filaments that need to be stored away from moisture, particularly Nylon, because they absorb moisture from the air and don't print well if they contain a lot of absorbed moisture.

Should I unload filament after printing?

You can leave your filament in a 3D printer if the environment isn't too humid or hot, otherwise, you can start to notice a decline in filament quality. Filament has a tendency to absorb moisture in the air, especially Nylon & Polycarbonate, so measure your humidity and try to keep it in a low range.

What can I do with small amounts of filament?

Just because the filament you have isn't enough for a complete print doesn't mean you can't use it for a 3D print; all you have to do is start a print and keep an eye on it and swap it out for more filament before it runs out.

How long does PLA filament last after opening?

Thus, a 1-kg spool of PLA should last you about 14 to 25 weeks, which equates to 4 to 6 months! Keep an eye on shipping costs, and make sure to order filament so that it arrives about 4 months after your last spool purchase.

Should I vacuum seal filament?

Keeping filament in an airtight container is a must to prevent the absorption of humidity from the air, and the use of vacuum-sealed containers or ones with desiccant is even better.

Is melting PLA toxic?

PLA filament fumes When you melt PLA filament, it releases Lactide into the atmosphere. This is a non-toxic chemical, however, and is relatively safe to be around. PLA is a low emitter of VOCs and UFPs as compared to other 3D printing filaments.

Can a hairdryer melt PLA?

And while it might seem like a hairdryer would be a good alternative to a heat gun, a hairdryer isn't designed to be hot enough to melt plastic (most models don't even reach PLA's glass transition temperature of 60 °C), so you'll be waiting a long time to see any change!
